This second book in the Trueblood series blows away the first. And though these books can be read separately, I'm glad I read them in order. Book 1 does a great job of supplementing the scene between Alek and his brother in this book. The struggle in the beginning, Alek pinned in the heart, trapped in a hole with Jo, created a delicious combination of frustration and tension. Add to that the introduction of shifters, this vampire series morphs into a thrilling and unpredictable adventure. I love that Jo was clueless about her biology. It allowed me to discover her heredity and her abilities right along with her. This dive into Jo's character funneled me into her life, locking me into that page-turning dream state I thrive for. And, ahhh, the quality and style of romance in this story is a skill Elsborg has impressive command of.
