Book excerpt: When Sierra Evans gave her twins up for adoption, she didn't expect tragedy to leave them in the care of their uncle, a notorious millionaire playboy. Now Sierra will stop at nothing to protect her children--even if it means going undercover as the perfect nanny...with a perfectly shocking secret. Former hockey player and entrepreneur Coop Landon can tell when someone's running a game. Clearly, his new nanny's not after his money or fame. Discovering her scheme is a challenge he's more than ready for, especially when seduction is the winning strategy. But the truth might cost them both dearly....
