Maelstrom: A Prince of Evil by Lorian Merriman
Maelstrom is a half-demon prince pining for a place in history. (Honestly, he’s just bored and searching for a way to pass the time.) Twigs is the young, prophesized Hero of Virtue fated to face him―or so we’ve been told . . .
But Maelstrom’s mother, regent to the throne and a powerful necromancer, is determined to keep an iron grip on her domain. Bemoaning his lost destiny, Maelstrom teams up with the Hero to stop his mother and forge a new destiny for himself. What Twigs doesn’t know is that Maelstrom has a cunning plan to build his own epic legend and double-cross Twigs at the perfect moment. . .-Goodreads
