Shifter Planet Series, Book 1

Amanda Sumner is one of the first to make contact on the planet Harp. The planet is Earth-like, but the forest is strange—she can hear the trees singing. And she's the only Earthling with that ability.

But the tree's songs have secrets, and to learn them all, Amanda will need to become a member of the elite Guild, the only woman to have ever done so.

Shifter Rhodry de Mendoza wants all the Earthlings off his planet before they destroy it, and he'll do anything to make that happen, even deny what he feels for the fierce and lovely Amanda. But Amanda has enemies that want her dead. If she and Rhodry are to live in peace, they'll have to fight for their lives, together.
