For Adan d'Amato and Lyan d'Vesti, only a shared bond-mate will ensure the continuance of their race. The Council scientists have found a match in Krista Thomas—a genetically compatible human. By Council rules Krista must be willing and the binding must be done immediately before she is brought back to their world, because once she accepts the bond, she will know that Adan and Lyan are not natives of Earth. For the warriors, it's a simple quest—go to Earth, bind their mate to them, then return home. There's only one catch—Krista is on the run and she's afraid to involve anyone else in her life.
