Spike appears significantly in a number of canonical Expanded Universe literature concurrent with and subsequent to the television series, including both "Buffy" and "Angel" comic books. Many of these novels and comic books concern Spike's backstory in the periods between the events shown in flashbacks in the television series. From 2007, both Dark Horse Comics and IDW Publishing began telling canonical continuations of "Buffy" and "Angel", respectively. Marsters himself wrote for the miniseries "Spike & Dru" in 2000. The collection also featured the Christopher Golden stories "The Queen of Hearts", "All's Fair", "Paint the Town Red" and "Who Made Who?", set in or around episodes of "Buffy" in seasons 2 and 4; "Who Made Who" is set during the "Buffy" episode "Lovers Walk" and depicts the disintegration of his relationship with Drusilla when they were together in Brazil. After "Buffy" finished in 2003, Spike appeared in a comic story from the canonical "Tales of the Vampires" series. Written by series writer Drew Goddard, "The Problem with Vampires" establishes his adventures in Prague prior to his introduction "Buffy" episode "School Hard". Christopher Golden's 2000 novel "" depicts Spike killing a Slayer named Sophie in the 1940s, contradicting the two Slayers whom Spike is later established to have killed; the second Slayer Spike killed was established as New Yorker Nikki Wood. The short story "Voodoo Lounge" from the collection "Tales of the Slayer" is a sequel to this novel. Golden's 2006 novel, "Blackout", is truer to the series' chronology by depicting Spike's fatal encounter with Slayer Nikki Wood in 1977. Diana G. Gallagher's 2005 novel "Spark and Burn" depicts the struggling early-season 7 Spike remembering an account of his life, amounting to a chronological character history of Spike's life from the 19th century to the time of the framing device.
