Everworld is a fantasy novel series co-authored by Katherine Applegate and her husband Michael Grant, writing together under the name K. A. Applegate, and published by Scholastic between 1999 and 2001. It consists of twelve books and a companion music CD titled The Everworld Experience. Main characters David Levin: The self-appointed leader of the protagonists. David takes on all the burdens of the group, and has been troubled by his past in which he was cowardly; he must prove himself to be a man. Before being sucked into Everworld, he was involved in a romantic relationship with Senna Wales. As such, he is most susceptible to the influence of Senna's powers. He shows his courage and bravery before Zeus, other gods, and Vikings. David fights with the Sword of Galahad, after witnessing Sir Galahad's death. At the end of the series, he opts to stay in Everworld to help protect it, as well as to escape his mother's smoking and depression problems. David narrates #1: Search for Senna, #5: Discover the Destroyer, and #10: Understand the Unknown. Christopher Hitchcock: The reluctant clown of the group, Christopher often makes jokes specifically targeted towards the other members of the group (April (sexism), Jalil (racism), and David (antisemitism)). He does this to keep the others at a distance, so they won't get to know him. Christopher is, in his own words, on the road to becoming an alcoholic like his parents. However, he can be a jerk one minute, and a kind, caring person the next. Christopher gave up the offer to become an immortal because he failed to save the life of Ganymede, Zeus' male lover; blaming his failure on latent homophobia causes Christopher to fall into an alcoholic depression and is the turning point for his character. Christopher also decreases in his prejudice jokes when Keith, who is part of a group of racists and anti-Semitics that plan to overthrow the government, tries to recruit him. At the end of the series, he opts to stay in Everworld to avoid his parents' alcoholic nature, escape his younger brother's ridicule and abuse, and stay off the road to a possible alcoholic future. Christopher narrates #2: Land of Loss, #6: Fear the Fantastic, and #11: Mystify the Magician.
