A Demon in My Bed — Sarah Winters

A missing brother, mercenary demigoddesses and an unknown force pulling fate's strings are just a few of the hurdles facing Verrin when he wakes up in a dungeon one morning. As the son of a renegade Angelic Watcher, he was born ill-fated. Being summoned by a plump little sex kitten who was everything he liked in a woman should have been a stroke of luck... As a librarian, the most exciting choice Cassidy O'Neill usually has to make is what book to read next. She never expected an antique book to drop a dirty minded sex demon into her bed. Bound to his side until the summoning is fulfilled, Cass is determined not to lose her heart to Verrin - even if he is the sexiest man she's ever met. In a world where myths are reality, falling in love is a gamble even immortals hesitate to take.
