She has two options—join a Shifter clan by choosing a mate or live alone. Life is dangerous for a woman after the extraterrestrial invasion. Women choose protection in a group or are sold into slavery, even to the aliens. She opts for the protection of the clan, him. He's glorious. Empathetic. And resolved to mark her. He will not lose her. Jackal, the powerful right-hand Shifter of the clan's leader, her brother-in-law, is determined she will be taken care of properly as mates aren't easily come by. Especially in The Wild. But they just met, and she fights mating in her early stages of mourning. Honor-bound with a vow made over his brother's death bed to see her safe, he internally swears to win her love. Whatever it takes. But she harbors a dangerous secret. Born a Cougar, she dares not risk revealing she's a Shifter, or bounty hunters will descend upon the remote mountain village to capture her for extraterrestrials. Villagers would die in the attacks. However, her Cougar rises up to claim Jackal for its mate. Shifter meets Cougar. Cougar claims her mate. Never-ending fireworks mark their raw attraction. But when the post-apocalyptic world is determined to tear them apart, will Normals, Shifters, or aliens win? Bet your money on COUGAR.
