Pinky Kumar wears the social justice warrior badge with pride. From raccoon hospitals to persecuted rockstars, no cause is too esoteric for her to champion. But a teeny tiny part of her also really enjoys making her conservative, buttoned-up corporate lawyer parents cringe.

Samir Jha might have a few . . . quirks remaining from the time he had to take care of his sick mother, like the endless lists he makes in his planner and the way he schedules every minute of every day, but those are good things. They make life predictable and steady.

Pinky loves lazy summers at her parents’ Cape Cod lake house, but after listening to them harangue her about the poor decisions (aka boyfriends) she’s made, she hatches a plan. Get her sorta-friend-sorta-enemy – who is a total Harvard-bound Mama’s boy – to pose as her perfect boyfriend for the summer.

When Samir’s internship falls through, leaving him with an unplanned summer, he gets a text from Pinky asking if he’ll be her fake boyfriend in exchange for a new internship. He jumps at the opportunity; Pinky’s a freak, but he can survive a summer with her if there’s light at the end of the tunnel.

As they bicker their way through lighthouses and butterfly habitats, sparks fly, and they both realize this will be a summer they’ll never forget.
