Chronicles of Fate and Choice, book 2: TumultusKate Sarah Turner2010

Who will fall? All worlds collide into our world, creating the ultimate war. The black-winged ones find their way back to Earth, returning with vengeance in their hearts and a plan that cannot fail. Darkness flies with them, casting shadows in the hearts of the weak and testing the loyalty of all. From the wreckage of the great war hope is born, but only after the heart-wrenching sacrifices of many. Left with only a handful of renegades, Tumultus follows the human Tachra and a band of courageous kutu warriors as they fight to maintain balance and save humanity, and themselves, from destruction. Their fates and their choices will make our futures.
