Question: Which 1985 novel was set in medieval England and featured four distinct royal houses?

full_context: Document 1: Capetian-Plantagenet rivalry: The conflict between the dynasties of the Capetians and Plantagenets covers a period of 100 years (1159-1259), during which the Kingdom of France fought against the Angevin Empire. This conflict is also called by some historians, the "First Hundred Years War." The conflict is primarily French, since both dynasties were French, the nobles that made up the English army were essentially of French origin, and the foot soldiers of the English king were local recruits in France (Anjou, Guyenne, Normandy, Brittany etc.). At this period, the English king's continental possessions were considered more important than his island possessions, and significantly greater than even those of the French sovereign, even if the latter was the overlord of the former for most of the possessions he held on the continent. And the official language of the two belligerents is the French of that time. French also remained the official language of England until 1361. Such is the origin of the expressions that can still be found today on the shields and coat of arms of the English monarchy "Honi soit qui mal y pense" and "Dieu et mon droit". The English kings, who were of French origin, took wives from France from the 11th to the 15th century. Very rare are those who married a woman of another country, including the cadet branches. Hence the Plantagenet monarchs were ethnically French.
Document 2: House of York: The House of York was a cadet branch of the English royal House of Plantagenet. Three of its members became Kings of England in the late 15th century. The House of York was descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III, but also represented Edward's senior line, being cognatic descendants of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that they claimed the English crown. Compared with the House of Lancaster, it had a senior claim to the throne of England according to cognatic primogeniture but junior claim according to the agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick in 1499.
Document 3: Henry II of England: Henry II (5 March 1133 – 6 July 1189), also known as Henry Curtmantle (French: "Court-manteau" ), Henry FitzEmpress or Henry Plantagenet, ruled as Count of Anjou, Count of Maine, Duke of Normandy, Duke of Aquitaine, Count of Nantes, King of England and Lord of Ireland; at various times, he also controlled Wales, Scotland and Brittany. Henry was the son of Geoffrey of Anjou and Matilda, daughter of Henry I of England. He became actively involved by the age of 14 in his mother's efforts to claim the throne of England, then occupied by Stephen of Blois, and was made Duke of Normandy at 17. He inherited Anjou in 1151 and shortly afterwards married Eleanor of Aquitaine, whose marriage to Louis VII of France had recently been annulled. Stephen agreed to a peace treaty after Henry's military expedition to England in 1153, and Henry inherited the kingdom on Stephen's death a year later.
Document 4: House of Plantagenet: The House of Plantagenet ( ) was a royal house which originated from the lands of Anjou in France. The name Plantagenet is used by modern historians to identify four distinct royal houses – the Angevins who were also Counts of Anjou, the main body of the Plantagenets following the loss of Anjou, and the houses of Lancaster and York, the Plantagenets' two cadet branches. The family held the English throne from 1154, with the accession of Henry II, until 1485, when Richard III died.
Document 5: The Pillars of the Earth: The Pillars of the Earth is a historical novel by Ken Follett published in 1989 about the building of a cathedral in the fictional town of Kingsbridge, England. It is set in the middle of the 12th century, primarily during the Anarchy, between the time of the sinking of the "White Ship" and the murder of Thomas Becket. The book traces the development of Gothic architecture out of the preceding Romanesque architecture, and the fortunes of the Kingsbridge priory and village against the backdrop of historical events of the time.
Document 6: List of legendary kings of Britain: The following list of legendary kings of Britain derives predominantly from Geoffrey of Monmouth's circa 1136 work "Historia Regum Britanniae" ("the History of the Kings of Britain"). Geoffrey constructed a largely fictional history for the Britons (ancestors of the Welsh, the Cornish and the Bretons), partly based on the work of earlier medieval historians like Gildas, Nennius and Bede, partly from Welsh genealogies and saints' lives, partly from sources now lost and unidentifiable, and partly from his own imagination (see bibliography). Several of his kings are based on genuine historical figures, but appear in unhistorical narratives. A number of Middle Welsh versions of Geoffrey's "Historia" exist. All post-date Geoffrey's text, but may give us some insight into any native traditions Geoffrey may have drawn on.
Document 7: Wars of the Roses: The Wars of the Roses were a series of wars for control of the throne of England fought between supporters of two rival branches of the royal House of Plantagenet: the House of Lancaster (associated with a red rose), and the House of York (whose symbol was a white rose). The conflict lasted through many sporadic episodes between 1455 and 1487; however, there was fighting before and after this period between the houses. The power struggle ignited around social and financial troubles following the Hundred Years' War, combined with the mental infirmity and weak rule of Henry VI which revived interest in Richard of York's claim to the throne. Historians disagree about whether the Wars of the Roses were caused by the structural problems of feudalism or Henry VI's ineffectiveness as king.
Document 8: Royal Arms of England: The Royal Arms of England are the armorials (or coat of arms) first adopted in a fixed form at the start of the age of heraldry (circa 1200) as personal arms by the Plantagenet kings who ruled England from 1154. In the popular mind they have come to symbolise the nation of England, although according to heraldic usage nations do not bear arms, only persons and corporations do. The blazon of the Arms of Plantagenet is: "Gules, three lions passant guardant in pale or armed and langued azure", signifying three identical gold lions (also known as leopards) with blue tongues and claws, walking past but facing the observer, arranged in a column on a red background. Although the tincture "azure" of tongue and claws is not cited in many blazons, they are historically a distinguishing feature of the Arms of England. This coat, designed in the High Middle Ages, has been variously combined with those of the Kings of France, Scotland, a symbol of Ireland, the House of Nassau and the Kingdom of Hanover, according to dynastic and other political changes occurring in England, but has not altered since it took a fixed form in the reign of Richard I (1189–1199), the second Plantagenet king.
Document 9: House of Lancaster: The House of Lancaster was the name of two cadet branches of the royal House of Plantagenet. The first house was created when Henry III of England created the Earldom of Lancasterfrom which the house was namedfor his second son Edmund Crouchback in 1267. Edmund had already been created Earl of Leicester in 1265 and was granted the lands and privileges of Simon de Montfort, 6th Earl of Leicester, after de Montfort's death and attainder at the end of the Second Barons' War. When Edmund's son Thomas, 2nd Earl of Lancaster, inherited his father-in-law's estates and title of Earl of Lincoln he became at a stroke the most powerful nobleman in England, with lands throughout the kingdom and the ability to raise vast private armies to wield power at national and local levels. This brought himand Henry, his younger brotherinto conflict with their cousin Edward II of England, leading to Thomas's execution. Henry inherited Thomas's titles and he and his son, who was also called Henry, gave loyal service to Edward's sonEdward III of England.
Document 10: Edmund of Langley, 1st Duke of York: Edmund of Langley, 1st Duke of York, KG (5 June 1341 – 1 August 1402) was the fourth surviving son of King Edward III of England and Philippa of Hainault. Like many medieval English princes, Edmund gained his nickname from his birthplace: Kings Langley Palace in Hertfordshire. He was the founder of the House of York, but it was through the marriage of his younger son, Richard of Conisburgh, 3rd Earl of Cambridge, to Anne de Mortimer, great-granddaughter of Edmund's elder brother Lionel of Antwerp, 1st Duke of Clarence, that the House of York made its claim to the English throne in the Wars of the Roses. The other party in the Wars of the Roses, the incumbent House of Lancaster, was formed from descendants of Edmund's elder brother John of Gaunt, 1st Duke of Lancaster, Edward III's third son.

Lord Norwich is a British historian, author and peer. The book was published by Penguin Group in Great Britain.
