Having moved to Annapolis, Maryland, with her medievalist parents, high school junior Ellie enrolls at Avalon High School where several students may or may not be reincarnations of King Arthur and his court.

Elaine percebeu as coincidências entre sua vida e a lenda dos Cavaleiros da Távola Redonda. Mas são apenas coincidências. Em 'Avalon High, A Coroação - A Profecia de Merlin', ela já está se acostumando a ser a garota nova da escola - é aluna de honra, estrela da equipe de corrida e, ah, sim, namora o capitão do time de futebol, Will-lindo-de-morrer, que supostamente é a reencarnação do Rei Arthur. Mas quem se importa com lendas antigas sobre espadas e maldições quando tudo na sua vida está quase perfeito?

Avalon High seems like a typical high school, attended by typical students: There's Lance, the jock. Jennifer, the cheerleader. And Will, senior class president, quarterback, and all-around good guy. But not everybody at Avalon High is who they appear to be ... not even, as new student Ellie is about to discover, herself. What part does she play in the drama that is unfolding? What if the bizarre chain of events and coincidences she has pieced together means—as with the court of King Arthur—tragedy is fast approaching Avalon High? Worst of all, what if there's nothing she can do about it?

The exciting conclusion to Meg Cabot's magical Arthurian manga! Ellie has only one day left to get her boyfriend Will to truly believe he's the reincarnation of King Arthur, or the world will plunge into eternal darkness. But Will refuses to believe her! Meanwhile, the upcoming Homecoming game and dance have everyone distracted, especially Ellie. Some people aren't too happy about her Homecoming Queen nomination and are determined to cause trouble. Ellie's got to save her reputation and the world before the new moon on the night of Homecoming brings them all to a dangerous crossroad. If Ellie can't convince Will of his destiny, the world may never recover... This manga series of Arthurian legend and high school romance comes to a thrilling climax in this final volume. And just remember anything can happen if you believe!"
