This is book number 4 in the Mageverse series.
Gawain believes he needs Lark for one thing and one thing only—and it’s not her skill with magic. In the process, he plans to help her overcome her fear and show her the pleasure to be found in a vampire’s arms.
But even as passion sizzles between Lark and Gawain, a revenge-driven killer targets them. If he has his way, Lark, Gawain, and the world itself will pay the price.
