In the Moment by Kate Willoughby

When Jane Merrifield hears about the Grease-themed week at Camp Firefly Falls, she can’t sign up fast enough. The list of camp activities reads like her ideal vacation and she expects campfire sing-alongs, pajama parties, and hand-jive contests. What she doesn’t expect is to come face to face with the guy who broke her heart when she was seventeen.
Booth MacDonald is one of the top goalies in the NHL, in part because he’s able to move past his mistakes and focus on the moment, but breaking up with Jane is the one mistake he’s never been able to put behind him. He needs a second chance and if that means he has to submit to a makeover orchestrated by the all-male Pink Ladies so he can sing and dance like a prize idiot, so be it, because he and Jane belong together—chang chang changitty chang she bop, wah-oooh, yeah.
