When Dr. Liam Ericsson learns that an experimental treatment’s side effects could drive him into a primal frenzy, he prepares for the worst.

Then Cara walks into his fertility clinic to find a donor, and Liam can hardly keep his jaw off the floor. Not only is the woman he's obsessed with now single, but she’s determined to be a parent. The sooner, the better.

After an intimate exam, Liam can’t stop fantasizing about Cara, or giving her what she wants. Then the regression hits him – at just the wrong time.

Or, maybe it’s the perfect time. Cara is spread before him, and ready. Now, no one else will claim her but him. The natural way.
