Eventide. Meratis Trilogy, #2

Six months after he returns from his fictional world of Andvell, Jeff Powell is still plagued by nightmares, and an inability to write anything new. Cursed with permanent writer's block, and on the verge of losing the woman of his dreams, he feels his life can't get any more complicated. Until he comes home to find Jayden and Brady in his apartment with news that the evil sorcerer Raul is in Montreal.
In their search for the now-powerless villain, they find themselves cast back into Andvell, tasked by the Sisters with finding Raul before he regains his power and destroys the world. As far as Jeff is concerned, he has greater issues. Cassie has a new admirer, his characters are keeping secrets, and he has become the target of a silent assassin. Without his creativity, Jeff doesn't know if he's up to the challenge.
If he wants to save his world from ruin, he needs to prove he has more to offer than his imagination. The Meratis Trilogy centres around author Jeff Powell, who wakes up in his sword-and-sorcery fantasy world. Initially an arrogant and close-minded character, Jeff has his eyes opened to a world of dragons, magic, and assassins. Faced with an evil he could never have imagined, Jeff is pushed to his limits and forced to rise to the most unusual challenges.
