Taming the Darkness - Love & Monsters, #2

He used to fight monsters. Now he is one. Love & Monsters, Book 2 Claire Scarlotti enters a top secret new program, hoping to make a difference in humanity's struggle against the terrifying nasties. But her new partner is going to be difficult. Especially at night, when he turns into the very thing she's supposed to fight. Claire needs to keep him close... and her gun closer. Victor Monroe volunteered to test a vaccine and ended up a monster.
Half-nasty and half-human, he can't always control his actions-or his desires. At first he tries to drive Claire away to protect her, but her touch is a human connection he desperately needs to tame the beast inside him. If they can't prove that Victor and others like him could be a valuable weapon against the nightmarish creatures that roam the world, they'll be worse than failures. They'll be dead. Warning: Contains monsters, violence, a kick-ass heroine, a hero on the edge of sanity, lab experiments gone wrong, unexpected tenderness, and safe sex that involves chains.
