Three of Spades (Hamden #2)
W. Ferraro

There is one catch. He has to play the part of Natalie's madly in love boyfriend for her dying mother. Dylan signs on, and finds that separating the two is harder than he thought. Natalie's days of shyness and lack of confidence come to a quick close as she learns what her body craves and demands in the bedroom.
Soon, Dylan becomes the student as Natalie teaches him things he didn't even know he wanted. Will Hamden's notorious playboy, bachelor be able to keep calling the shots, or will he find that, he, himself, is just another player at the card game of life, as we all are?
