Only on Gameday (Paperback) (ISBN-13: 9781335661289)

An all-new GAME ON sports romance from BookTok sensation and New York Times bestselling author Kristen Callihan with high emotional stakes and a slow-burn, steamy heat level.

A 'fake' wife is just the trick to help a bad-boy football player clean up his image and let his career take off. Trouble is, there's nothing 'fake' about the way August feels about his pretend wife. Game on.
August Luck, known to fans as "Luck", is on the brink of greatness: top draft pick, tons of money heading his way, talent galore, but he keeps messing it up with bonehead moves and looking out of control in public. Problem is, he can't get out of his own way. To clean up his image and calm him down, his agent decides Luck needs a temporary 'wife'.

Penelope Marrow, the girl next-door he's known since they were kids, is the safe option. Pen is the only person who's ever put him in his place, and she disapproves of him, so there's no chance she'll cling. He didn't count on wanting her to stay. Question is, will she play ball? Just the idea turns his knees to jello.
