Zorak - Lunar Uprising, #1

When Cat's father is kidnapped by her alien boss she turns to Zorak, one of the mysterious lunar raiders "cultivated" by the aliens to protect Earth. Cat isn't sure she can trust Zorak, but she has nowhere else to turn. Lunar raiders are ruthless hybrids created for war, so why does Zorak make her feel safe? She has never been so intensely attracted to anyone before and has a hard time believing her feelings are real.
They're surrounded by conflict and deceit, and Cat's father isn't the only one in danger. If they can't learn the truth about the aliens, the entire human race could be enslaved.
