Demon Thief is a book in Darren Shan's "Demonata" series.
 Though it is the second book in the series, it is a prequel to "Lord Loss", the first book in the series.
 The protagonist is also different from that of the first book.
 The narrator here is a new character called Kernel Fleck, as opposed to Grubbs Grady, the protagonist of the first book.
 Demon Thief takes place about thirty years before "Lord Loss" so most of the characters from the first book did not appear, though a few did.
 It was also actually the sixth book of the Demonata to be written, although it was the second released.
Murat Gülsoy (born 1967) is a Turkish writer.
 He started his literary career as a publisher and a writer of the bimonthly magazine "Hayalet Gemi" (Ghost Ship) in 1992.

 He also produced interactive hypertext works on internet exploring new ways of narrative.
 Gülsoy has published 18 books in Turkey so far.
 Besides short stories, he has eight novels addressing modern masters Kafka, Borges, Eco, Laurence Sterne, Fowles and Orhan Pamuk.

 His novels are published in English, Macedonian, Arabics, Bulgarian, Albanian and Chinese.
 His 2000 Sait Faik Award-winning book "Bu Kitabı Çalın" (Steal This Book) ironically "borrows" (or steals) its name from Abbie Hoffman's 1971 book "Steal This Book" and it is referred in the book as a postmodern parody.

Stig Riemmbe Gaelok is born July 7, 1961 in Divtasvuodna / Tysfjord.
 He is an Sáme author, who writes his books in Lule Sáme language (julevsámegiella) and Norwegian language (norsk).
 His first book, the poetry collection "O, Oarjjevuodna", which was published in 1983, was the first collection of poems ever in Lule Sáme language, and also the first book in Lule Sáme language since ´s book "Jåhttee saamee viessom", which was published 46 years earlier, in 1937, and was the first book ever written of a Lule Sáme in Lule Sáme language.
18 Poems is a book of poetry written by the Welsh poet Dylan Thomas, published in 1934 as the winner of a contest sponsored by "Sunday Referee".
 His first book, "18 Poems", introduced Thomas's new and distinctive style of poetry.
 This was characterised by tightly metered, rhyming verse and an impassioned tone.
 Written in his "womb- tomb period", the poems explore dark themes of love, death and birth, employing a rich combination of sexual connotations and religious symbolism.
 The lyricism and intensity of the poems in the book contrasted with the emotional restraint shown in the poetry of the successful modernist poets that worked as his contemporaries.
 The book received critical acclaim, but was not initially commercially successful.
The Dancing Wu Li Masters is a 1979 book by Gary Zukav, a popular science work exploring modern physics, and quantum phenomena in particular.
 It was awarded a 1980 U.S. National Book Award in category of Science.
 Although it explores empirical topics in modern physics research, "The Dancing Wu Li Masters" gained attention for leveraging metaphors taken from eastern spiritual movements, in particular the Huayen school of Buddhism with the monk Fazang's treatise on The Golden Lion, to explain quantum phenomena and has been regarded by some reviewers as a New Age work, although the book is mostly concerned with the work of pioneers in western physics down through the ages.
Censorship in Afghanistan is a book by Hazara poet and journalist Kamran Mir Hazar.
