Mark Anthony learned to love both books and mountains during childhood summers spent in a Colorado ghost town. Later he was trained as a palaeoanthropologist but along the way grew interested in a different sort of human evolution - the symbolic progress reflected in myth and the literature of the fantastic. He undertook the LAST RUNE series to explore the idea that reason and wonder need not exist in conflict. Mark Anthony lives and writes in Colorado.

50 Cent (a.k.a. Curtis Jackson) is a record-breaking rap recording artist, entrepreneur, music producer, and actor. His debut album, Get Rich or Die Tryin’, sold more than 12 million units worldwide, is certified eight times platinum, and was the basis for the semi-autobiographical film of the same title, in which he starred. He is the first artist to have four songs in the top ten of Billboard’s Hot 100 since the Beatles in 1964. He published his memoir, the New York Times bestseller From Pieces to Weight, which was hailed as “cool, hard, and vivid, a minor classic of gangster rap noir” (The New York Times). He is also the author of Hustle Harder, Hustle Smarter. Under the G-Unit brand, his business empire includes a record label, apparel and footwear ventures, vitamin water, and more. He created the nonprofit organization The G-Unity Foundation, which aims to better the life of urban youth. Follow him on Twitter and Instagram at @50cent.
