Wolf's Surrender Publisher's Summary
Total surrender doesn't come easy to a natural-born alpha. Shape-shifting special operative Brad Durant has been held against his will by the enemy for nearly a year. He's given up hope and is fast giving up his will to survive - that is, until a hot-tempered, redheaded succubus is placed in the cell next to his. She calls to his wolf on a primitive level and he won't let anyone or anything harm her. Giving his body to the little minx is easy, but guarding his heart is much harder.
