You've fallen in love with a man as beautiful as the moon and a man as hot as the sun.
Guest has lived her life as a human. In the rainy town of Forks, her daily life begins to quietly crumble following an encounter with two supernatural beings. One is Cedric, a vampire who reads human hearts and lives in eternal solitude. The other is Kyle, a werewolf who harbors wildness and heat, living to protect what he holds dear. Two hostile races. A single human standing between them. "I will protect you." Faced with these two men, what answer will Guest choose? This is a story of a vampire who lives for eternity, a werewolf who lives by instinct, and a girl who chooses her own destiny.

Eyes are amber. His physical abilities are in a different league, and he can overwhelm several young werewolves at once. However, the reason he is truly feared is not his strength.

However, if he says a single word, "Stop," even the young werewolves fall silent.
