Question: Sky of Stone is the third in a trilogy of memoirs that began with the first book October Sky, about growing up in a mining town, written by who?
Context: Reed's Store is a historic building located at 679 Main St. in Copperopolis, California.  William K. Reed, a miner and one of the first discoverers of copper in Copperopolis, built the store in 1861 to serve the growing mining town.  The two-story brick store was designed in the Neoclassical style, a common design for commercial establishments at the time.  Reed's Store was the most successful store in Copperopolis until 1867, when a fire and the declining copper industry greatly diminished the town's population.  Various lessees rented the store until mine owner Charles Ames bought it in 1890; Ames sold the store to merchant Charles Fontana by 1900.  In 1906, the store became the property of the Union Copper Mining Company, which made the building its headquarters.  The company, later renamed the Calaveras Copper Mining Company, occupied the building throughout the town's 1909–1929 copper boom.  The store is now one of four buildings remaining from the 1860s in Calaveras; it is adjacent to two others, the Copperopolis Armory and the Honigsberger Store. Hell Isn't My Home is the debut full-length studio album by October Sky, released on September 2, 2008.  It was originally released independently on October 10, 2007, but was released officially as a double album under TRX Distribution, a Quebec-based record distributor.  The second disc is a bonus disc which features the first three songs of the band's first EP October Sky EP.  In 2009, the company was bought out by DEP under Universal Music Canada, and October Sky and Universal failed to reach an agreement to continue distributing the album. Hernán Rivera Letelier (born 11 July 1950 in Talca, Chile) is a Chilean novelist.  Until the age of 11 he lived in the Algorta saltpeter mining town.  When it was closed down, he and his family moved to Antofagasta, where his mother died.  His siblings went to live with his aunts.  He stayed in Antofagasta, alone, until he was about 11.  To survive, he sold newspapers.  Later he worked as a messenger for Anglo Lautaro Nirate Company, until his thirst for adventure led him to spend three years traveling in Chile, Bolivia, Perú, Ecuador and Argentina.  He returned to Antofagasta in 1973 and began to work at another company, Mantos Blancos.  He married a 17-year-old girl when he was 24.  Later he left for Pedro de Valdivia, another saltpeter mining town.  He completed his seventh and eighth years of study at night school, and at the Inacap educational institute he earned his license as a secondary education instructor.  Today he lives in Antofagasta with his wife and four children.  He has received the "Premio Consejo Nacional de Libro" (Chilean National Book Award) twice, in 1994 and 1996.  His novel "El arte de la resurrección" won the Premio Alfaguara de Novela in Spain in 2010. Sky of Stone is the third in a trilogy of memoirs by Homer Hickam, Jr. about his hometown of Coalwood, West Virginia, that began with "October Sky". Stone and Sky is a fantasy novel written by Graham Edwards.  The novel was first published in 1999 by Voyager Books (UK) and HarperPrism (US).  It is the first book in the Stone trilogy, which also includes Stone and Sea and Stone and Sun.  The trilogy is a follow-up to Edwards' Ultimate Dragon Saga trilogy, and is loosely connected via various plot threads. October Sky (originally published as Rocket Boys) is the first memoir in a series of three, by Homer Hickam, Jr. It is a story of growing up in a mining town, and a boy's pursuit of amateur rocketry in a coal mining town.  It won the W.D. Weatherford Award in 1998, the year of its release.  Today, it is one of the most often picked community/library reads in the United States.  It is also studied in many school systems around the world.  "October Sky" was followed by "The Coalwood Way" (2000) and "Sky of Stone" (2002). Delaware is an unincorporated community in Keweenaw County in the U.S. state of Michigan.  It was established in 1846 as a copper mining town.  It is located in the Keweenaw Peninsula, ten miles south of Copper Harbor and around twenty five miles north of Calumet.  When the town was first settled it had a population of one hundred and rose to a population close to 1200 during full operation.  When the town first started out the mining companies brought everything including housing, mining buildings, schools, grocery store, and a church.  Today all that is left is a mining tour and foundations of old mining buildings.  This is mostly because there were no other jobs and the location of the town is in a very remote location.  The town made attempts to survive but in the end did not make it.  The Bete Grise Light is located in the area. October Sky EP is October Sky first studio recording, which was self-released on September 23, 2006. Tlalpujahua (    ; formally Tlalpujahua de Rayón) is a town and municipality located in the far northeast of the state of Michoacán in central Mexico.  It is a former mining town, home of the Dos Estrellas Mine, which was the leading producer of gold in the early 20th century.  A major landslide of mud and mining debris damaged this mine and buried about one-third of the town in 1937, effectively ending mining.  In the 1960s, a local by the name of Joaquín Muñoz Orta began making Christmas tree ornaments here.  This eventually grew into what is now one of the largest producers of ornaments called Adornos Navideños SA de CV.  In addition to this and another factory, there are about 150 small workshops dedicated to making Christmas items, with about 70% of the town’s economy based on it.  In 2005, the town, with its narrow stone streets and adobe/stone houses with red tile roofs, was made a Pueblo Mágico as part of its efforts to attract tourism. The Coalwood Way (2000) is the second memoir in a series of three, by Homer Hickam, Jr. "The Coalwood Way" is a story of the Rocket Boys and Coalwood.  Homer calls it an "equal," rather than a sequel because the story happens during the same timeframe as the first book.  Today, it is one of the most often picked community/library reads in the United States.  It is also studied in many school systems around the world.  The Coalwood Way (2000) is followed by "Sky of Stone" (2002), and preceded by "October Sky" (1998).
