This is the sixth installment in Castle/Krentz's Harmony series which has links to Krentz's Arcane society books with psychic abilities and in common ancestors.
The Dores were famous for their luck bad luck, that is and Lyra is a true Dore. Three months ago, she located an ancient amethyst ruin deep in the rain forest on planet Harmony, but she was swindled out of her claim by the CEO of Amber, Inc., Cruz Sweetwater, the man Lyra just happened to be dating at the time. Though she didn't know it as he used a fake name. Hence their big breakup.
Now Cruz needs Lyra to help free some of his employees, who have become trapped in the ruin. Cruz is the last person in the world Lyra wants to help, but she isn't about to let five people suffer just because their boss is a jerk. Working with Cruz proves to be a bit difficult, though, once Lyra discovers Cruz believes she is his true love, and that he now wants her back in his life, for good.
I've been reading her books set in Harmony for about 15 years and it was nice to read one that is back to the fun yet somewhat suspenseful romance atmosphere.
