The newest book in Kristen Callihan's fan-favorite GAME ON world delivers an emotionally charged NFL romance with a fake engagement, childhood-friends-to-lovers tension, and the kind of slow-burn yearning that will wreck you. Perfect for fans of Elle Kennedy and high-heat sports romance.

A "fake" fiancée is just the trick to help a bad-boy football player clean up his image. Trouble is, there's nothing fake about the way August feels about his "pretend" fiancée.

August Luck is on the brink of greatness: #1 NFL draft pick, a new starting quarterback role, and a future everyone expects him to dominate. But he keeps making headlines for all the wrong reasons. After his latest stunt goes viral, everyone agrees: he needs to get it together.

Penelope Morrow grew up alongside August. Their mothers were best friends. The Luck family practically raised her. But August barely spoke to her, and Pen was always too shy to do anything but flee the room when he walked in. She's spent years convinced he couldn't stand her. He's spent years convinced of the same.

When Pen inherits her grandparents' house but can't afford the estate tax, August sees an opportunity: a fake engagement that solves both their problems. He cleans up his image. She keeps her home. Simple.

Except nothing about Pen has ever been simple for August. And the longer they pretend, the harder it gets to keep the truth buried: this was never fake. Not for him. And maybe not for her either.

All's fair in love and football…game on.
