The Jock and the Geek by Sidney Bristol

Samantha Grant is at a dead end in life. Fired from her job because her father happens to be the Secretary of State is just the icing on the cake. At least she has Monster-Go to fill her empty hours. Except she’s not the only one playing the augmented reality phone game. Her ex, the jockiest jock of all is, too. And he just happens to be on the rival team. She’ll take this competition to a whole new level in the name of winning the title as the best Monster Master in the Capital.

Oliver Falcón is in love with his boss’ daughter. The problem is, she hates him with the passion of a thousand, fiery suns. He broke her heart to protect her once, and now he wants her back. Strategy has always been his gift, and this time he’s got a plan to not only win Sam back, but show her just how much he belongs in her world. He’s gone geek, and he’s never going back. Past secrets haunt the former lovers, and as much as Oliver wants Sam back in his arms, he’ll break her heart again if it means protecting her.
