Adopted and raised by Terrans, Dr. Brianna Martin never quite fit in. She's thrilled to learn she's a long-lost female of the Prime race. And that she has a mate living somewhere on the planet Cejuru Prime-one genetically destined to be hers alone. Before she figures out how to approach him, she's attacked in her research lab. Iolyn Caradoc is stunned at the news that his mate, matched to him soon after birth, still lives. Even more amazing, she's a research scientist on the verge of discovering why the Prime race is dying. But Pure Blood fanatics are trying to kill her and she's on the run. Every primal instinct in him insists he find, claim, and protect his mate. But the woman won't stay put. When Bria finally meets Iolyn, she's thrilled. He's everything she could want-physically strong, highly intelligent, and ... the other half of her soul. Yet, he's also an overwhelmingly dominant and stubborn Prime warrior who wishes to protect her from everything-including her own Prime nature. As a Prime battle-mate, she has newfound instincts and skills-skills that will make her a true warrior. Skills she fully intends to learn and use. If she manages to survive.
