Dangerous Games by Claire Thompson

When you play dirty games, the stakes are dangerously high …
Reese Armstrong is striving to get his life on track. He has started a new career, gotten a new apartment…now he has to figure out how to shake the guy who insists on controlling his every move. For years, Reese took part in the deviant bets orchestrated by his wealthy lover, Hank. He’s told himself he’s done with all that, but the terms of this latest bet are more than Reese can refuse.
As head computer programmer at a software company, Luca Hartman’s professional life is soaring. But his personal life is a lonely mess. When the hot new sales guy takes an interest in him, a world of possibility opens. But Luca’s been burned before, and he’s wary of the sudden attention. Why would Reese, who could have any man he wants, choose geeky, stuttering Luca? Is he truly sincere or should Luca be on the lookout for a string of malicious code?
Disarmed and enchanted by the shy, brilliant Luca, Reese has to make a choice: reject Hank’s dirty tactics or follow through and destroy the potential he sees with Luca. But even if Reese wants to be done with their dangerous games, Hank’s not through with him…
