Almost twenty years have passed since Cain, the formidable T-Rex shifter, and his Ultimate Predators attacked the Shifting Sands Ranch. Jax, Dakota, and the rest of the Pack have matured and prospered. A new generation of shifters have come into their own at the Ranch, not least of which are twins Tai and Mal, who give their uncles no end of sass, just like teenagers should. Life is good, but the peace they've enjoyed is about to be splintered. Cain left behind more than just his mark on the lives of the folks at the Shifting Sands Ranch, and his twin legacies are vengeful, lethal, hungry, and headed for the Ranch, intent on finishing what Cain began. What happens when the next generation of shifters collide just like their parents' did? Who will survive? Who will come out on top? Find out in this exciting sequel to In Their Own Skins: Shifting Sands.
