 Vashama canem. Come back to me. 
 With these words, Ava brought back her mate though he's not entirely the same man. With spotty memories, Malachi tries to find his way back to the voice that has been calling out to him. Unbeknownst to Ava and her own power, she is led away to a haven for Irina for protection and to learn and control her power. 
 As Malachi returns to his brothers and get their help to find Ava, there's a power struggle between two Fallen angels, each with their own agenda for Ava. The Grigori numbers enmass in areas usually unseen and more questions arise as to their purpose. 
 While Ava grieves for her mate, you grieve with her even though you know they'll find their way back to each other. The emotions felt real even on Malachi's side as he struggle to understand what happened to him. They are each other's half and incomplete without the other. 
 More characters are introduced and you learn more about the Irin/Irina way of living. Intricately written, emotionally powerful, this one will leave you just as breathless as the first book. That epilogue didn't just slam a door open, it broke a dam for questions to flow through. While the ending didn't sit on a huge cliffhanger like in the first book, I'm still flabbergasted. Where is this going? Even as we have a name, the real identity is unknown. Is it who I think it is? I need to know! I need book 3!! 
 Highly recommended.
