Raised by humans, Kate has no idea she is from an alien race whose people have secretly lived among humans for centuries. That is, until she meets her shifter, her mate-of-the-eons, Aaron. While rescuing a child and his mother from an abusive kidnapper, Aaron has to work hard to convince Kate she's not human. Just as Kate realizes that she is indeed Permutant, she is abducted by a faction of her own people, the Transmutants, who wish to enslave humanity. In captivity, Kate learns that she is a high priestess and that her life depends on discovering her abilities and control of her mother's powerful stone. Fortunately, mates can mind-speak, so Aaron is able to help Kate, but will he survive sneaking into the heavily guarded Transmute caverns to be with her? Can Kate learn to wield her power for good while fighting the evil, depraved Arganon, who craves control of her power? Kate and Aaron must overcome challenges that no couple should have to endure. All they want is to be free to love each other, but that freedom is hard-won. Expect a complex plot fraught with intrigue, humor, battle, unexpected death, and, of course, love.
