The Prophecy - The Three Brothers Prophecy, #1

Seventeen-year-old Jack's entire life changes when he is summoned to his dying mother's room one fateful night. She reveals a long-forgotten prophecy of three brothers who would bring an end to a vampire queen, a werewolf king, and the great and powerful one. When Jack drinks from a mysterious vial, he finds himself transported five hundred years into the future, where he discovers that vampires and werewolves are real.
He is even more shocked to discover that his two brothers, Royce and Draco, are among them. Royce, a short-tempered vampire, has built an empire with his wealth and everlasting life. But when two obnoxious brothers and a young girl named Shaylie enter his life, his- world turns upside down. Suddenly, he must confront an evil that threatens to destroy everything he's worked for. Draco, a carefree werewolf, is living the dream as a rock star with all the trappings of success: a gorgeous girlfriend, adoring fans, money, and friends.
His biggest concern so far has been how to break it to his girlfriend that he's a werewolf. But when Jack appears in his backyard, unconscious and disoriented, Draco realizes that his world is about to change forever. Despite their differences, Royce, Draco, and Jack must come together to defeat their enemies, who threaten to destroy everything they hold dear. With no other choice but to fight, they will have to navigate new alliances and accept their destiny if they hope to emerge victorious.
Along the way, they will experience heartbreak, betrayal, and loss. But through it all, they will discover the true meaning of family and the power of brotherhood.
