Unless, first published by Fourth Estate, an imprint of Harper Collins in 2002, is the final novel by Canadian writer Carol Shields.
 Semi-autobiographical, it was the capstone to Shields's writing career: she died shortly after its publication in 2003.
 The work was widely acclaimed and nominated for the Booker Prize, the Giller Prize, the Governor General's Award, the Orange Prize for Fiction, and received the Ethel Wilson Fiction Prize.
 In 2011, it was a finalist in the Canada Reads competition, where it was defended by actor Lorne Cardinal.
 Like many of her works (especially The Stone Diaries), "Unless" explores the extraordinary that lies within the ordinary lives of ordinary women.

Lana is a female given name and surname.
 Though its origin is disputed, it can be found most frequently in the English speaking countries, Russia, as well as many other European countries.
 "Lana" can be short for Alana (in English) or Svetlana (in Russian), as well as a derivative of the Greek name Helen.

 After running two important art galleries in the 1930s and 1940s, he came to wider public notice on television, presenting a succession of series about the arts during the 1950s and 1960s, culminating in the series "Civilisation" in 1969.
Carol Ann Shields, {'1': ", '2': ", '3': ", '4': "} (née Warner; June 2, 1935 – July 16, 2003) was an American-born Canadian novelist and short story writer.

The term "panzer division" (German: "Panzerdivision" ) as commonly used in English language refers almost exclusively to the armored (tank) division in the army branch of the Wehrmacht and of Nazi Germany during World War II.
 The panzer divisions were the key element of German success in the Blitzkrieg operations of the early years of the war.
 Later the Waffen-SS formed panzer divisions, and even the Luftwaffe fielded a panzer division, the Herman Goring Division.
 The term "Panzerdivision" is still used in today's Army of the Bundeswehr (for example 1.
 Panzerdivision).
 In German speaking countries the term is not immediately associated with the Wehrmacht as it is in English speaking nations, as the word simply means 'armored division' and has no additional connotation.
Milica (Serbian Cyrillic: Милица; pronounced Millitsa) is a feminine name popular in Slavic countries.
 It is derived from the Slavic word element "mil(a)", meaning "kind" and "dear", with the diminutive suffix "-itsa".
 The name was used for a number of queens and princesses, including Princess Milica of Serbia, wife of Lazar of Serbia, who is honored as a saint in the Serbian Orthodox Church.
 Milica has been the most popular name for girls born in Serbia since 1991, and is overall the most common female given name in the country.
 The name is occasionally given the phonetic spelling "Militza" in English speaking countries.
 The name of Princess Milica of Montenegro was often translated as Militza in English language publications.
The name Chamorro may be both a patronym and a matronym.
 In Spanish speaking countries, the patronym is usually followed by the matronym to more precisely identify an individual (See Iberian naming customs).
 In English speaking countries, the matronym is frequently omitted, resulting in ambiguity.
 Omission of a given second or middle name further obfuscates an individual's identity.
Yatsko (in international transcription:[jɑːc'ko]; in English transcription: [jɑːts'ko]; Russian spelling: Яцко) is a Slavic surname that can be found in Russia, Belarus, Ukraine, the United States, Moldova and some other countries.
 In English speaking countries it is pronounced with the first syllable stressed [ˈjɑːtskoʊ] and has other less common variants of spelling: 'Iatsko', 'Jaczko'.
 The surname is rather rare and hasn't been listed among the most common surnames in the above-mentioned countries.
