Free Fall - Retrievers, #5

The Cosa Nostradamus is in disarray; the Truce that has kept the city peaceful for decades has been broken, and magical Manhattan is at war. In the midst of all this, Wren Valere is left without her partner Sergei, whose past loyalties - and betrayals - keep him from her side just when she needs him the most. Wren wants nothing more to do with violence. But for her community - human and otherwise - to survive, it's time for the Cosa to take the battle to the real enemy.
But they'll do it her way. Fast, smart, and sneaky. What was lost will be found, what was stolen will be Retrieved. And this war will be ended, once and for all. Wren Valere always finishes the job. Always.
