The Hatter mode and the Hare (Hacking Wonderland) by Lindt, Allyson NEUF

Hatter has made a career of keeping people at arms length.

He doesnt expect Reagan to throw a wrench in his plans, though. Intoxicating, brilliant, and incredible in bed, shes knocked him off-kilter in a way he never expected.

Hare has been called a lot of names in his time--fanatical, mad, and obsessive are at the top of the list. But hes so close to getting what he wants. No one stands in his way, until Reagan. Her view of the world is an odd blend of rose-colored cynicism, and the things she lets him--begs him to--do her body, haunt his dreams and darkest fantasies. But she could ruin his life if he doesnt move the chess pieces right.

Both men will risk their livelihoods, connections, and power to have her, but only one will kill if he cant.
