Saving Midnight

"Graham Fitz Clare became a vampire to save his adoptive father from a deadly enemy. Sadly, the price of that rescue may have been too high. Edmund's captors are at large, and are amassing the sort of power that could make them unstoppable. Now it's up to Edmund's family to defeat this dangerous foe. They'll have new allies and new weapons, but even this might not be enough. In the end, the love the Fitz Clares share with each other could be all that stands between them and a desperate storm of destruction" -- from author's web site.
