Ever since her younger sister's engagement was announced, Harper Williams has been dreading the wedding. What should be a joyous, sun-drenched affair is sure to be filled with plenty of awkward moments, thanks to Harper's strained relationship with her only sibling. Awkwardness enhanced by the wedding's location-a lake in Maine, swimming with painful memories of their late father.

Running into Drew Halifax-her childhood crush, who grew up to be the golden boy of hockey-is a surprise. Not nearly as shocking as his offer to be her plus-one is though.

She expects him to back out. He shows up. She's looking for a distraction from the past. He's killing time until his season starts and he can chase the championship. She's guarded yet outgoing. He's easygoing yet focused.

They hardly know each other. Until one week of sharing secrets, pretending to be in love, and sleeping in the same bed changes everything. Feelings that were supposed to be fake start to feel very real.

Problem is, neither of them is looking for a relationship. At most, they're meant to be a summer fling. Definitely not a happily ever after.

But when it comes to falling? You have no control. Once you start, it's impossible to stop. And sometimes...it takes six summers.
