Saving Charlie is an official tie-in novel for the US TV show Heroes that was published in 2007, in the gap between the show's second and third seasons (although it relates to the events of the first season). It is the only official tie-in novel that was published for the show, although other tie-in webcomics and graphic novels were also published. The novel revolves around an event in the show's tenth episode in which Hiro Nakamura accidentally travels too far into the past in an attempt to save the life of Charlie Andrews, a waitress who is killed by Sylar, one of the series' main antagonists. It extends the time that Hiro spends in the past as he searches for a way to avoid her death and travels back and forth in time, searching for clues, and further develops his relationship with Charlie.
