“In a word, THEHOLYCRAPBOMBYESMOREYES.” — LIA RILEY ,  USA TODAY  bestselling author, on  The Hook Up Kristen Callihan's  Game On  series Now in print with exclusive new bonus content! It’s lust at first sight in the fourth book of  New York Times  bestselling author Kristen Callihan's Game On series. Unreasonably sexy NFL star Finn Mannus plus a few guys from the team agree to do a charity calendar photo shoot—naked. With a name like Chess, Finn assumes the photographer is male. But when Chess opens the door to her studio, Finn’s confidence comes off as cocky arrogance. Even while in the buff, Finn manages to firmly plant both feet in his mouth, setting Chess’s teeth on edge. With their flinty chemistry, it’s going to be hard to keep things strictly professional. Kristen Callihan 's The Hot Shot is chock-full of delicious tropes, including: Lust at first sight Opposites attract Grumpy sunshine (she’s the grump) Friends with benefits Plus, a sexy playboy football star who wants a lot more, and a heroine who just…doesn’t.
