The Fiery Heart - Richelle Mead

I love this series. I love Adrian! With Sydney FINALLY letting go of her Alchemist prejudices, the ball really gets rolling with Adrian. 

Sydney's sister Zoe really throws a wrench in the works, as expected, leaving the reader with a cliff hanger ending. Silver Shadows is then next installment in the Bloodlines series, but frankly waiting until end of July is torture!
