Dark Defender (Paladins of Darkness, Book 2)

Alexis Morgan continues her dazzling paranormal series about larger-than-life warriors and the women they love.... As a Paladin warrior, Blake Trahern fights and dies again and again to keep mankind safe from the Others. Sensing his humanity slipping away with each battle, he retreats from the world...until the one person who still has a claim on his soul needs his help. It's been twelve years since Blake vanished from Brenna Nichols's life, years that have turned her from a love-struck teen into a headstrong, sensual woman. He'll fearlessly give his life to protect her -- yet he dare not risk his heart. Brenna is stunned by Blake's reappearance, and by a shocking discovery about her father. Everything she has ever believed is thrown into question -- everything except the desire that Blake still ignites. But as they search together for a traitor among the Paladins, danger looms: the next battle could tip Blake into madness, destroying his life, his soul...and the only woman he has ever loved.
