Sophia Reece is a genius geneticist who's isolated the link between shifters and their animals. Unfortunately, she's also a very shy and clumsy woman. That's never more evident than when she has a not so little accident with her lion and wolf samples and ends up becoming her own guinea pig. Watch out, those needles are sharp. Damn, shit just got real. Alpha wolf Chase knows Sophia is his mate. And if she weren't so shy and always running from him, he'd have made his move with her. He can't stop thinking about her sexy human body and how badly he wants to dip his tongue into all her curves. But when shy Sophia suddenly flashes golden eyes and smells of heat, he's not sure what's going on, but is more than ready to get her naked ASAP. Sophia isn't prepared for her first mating heat or the fact her feelings for Chase refuse to remain under wraps. When someone wants her research, she'll find out what she's really made of. Who says smart girls can't be alphas too? Things are a lot more complicated than being perfectly mated. The race is on to stop the bad guys from getting their hands on her work and staying alive. Sophia's about to learn that being in love doesn't stop someone from coming face to face with death.
