Clover Rivers is completely, totally over her ex.

Sure, her first ever relationship with a girl might have ended in a catastrophic breakup people still whisper about, but Clover is done with it.

The four years since have made her stronger. Smarter. Four years have turned her into the kind of woman who doesn't believe in wishes on stars or miraculous second chances. As an aspiring environmental scientist, Clover puts her faith in cold, hard data, and the data says there's no way anything good can come of messing around with a girl who already broke her heart.

Neavh Beaudoin is completely, totally still in love with Clover Rivers.

When a series of disasters lands her living on her cousin's couch—and back in the small island town she never thought she'd see again—Neavh is forced to confront the truth: leaving Clover behind was the biggest mistake of her life, and she'd give every star in the sky for another chance.

As cramped small town life makes it impossible to ignore the way the two women still spark like a wildfire, Clover realizes Neavh's reasons for leaving might not have been so straightforward, and the future she's planned for herself in the meantime might not fit as well as she thought.

The data suggests they're only in for another heartbreak, but every theory's got the tiniest chance to be proven wrong—especially when your last shot at love might depend on finally getting things right.

One summer can change everything.

At least, that's what Naomi has heard. Personally, she's not interested in changing anything. With the start of university looming like the Ghost of Adulthood Yet to Come, Naomi is ready to spend the most uneventful summer of her life house sitting for her dad's boss.

Her friends might be making epic summer bucket lists, but to Naomi, two months alone in a giant mansion sounds like just the escape she needs from the anxiety that's spent her whole life telling her change can't be anything but bad.

Andrea is ready for a change. Sure, she might have taken things a little too far by dumping her boyfriend, quitting her job, and breaking into her dad's seemingly empty house to spend the summer plotting her next move, but Andrea has never done anything by halves.

When she discovers the house is not, in fact, empty, and that the mysterious house sitter with the biggest blue eyes she's ever seen is hiding a secret summer bucket list, Andrea hatches a plan to tick the items off together.

It's the perfect trade: Naomi gets an accountability buddy, Andrea gets an excuse to avoid planning her own future for just a little longer, and once the list is complete, they go their separate ways.

It's simple, it's effective, and it definitely doesn't leave room for them to fall in love—no matter how many times they stay up all night talking, or how good it feels when their hands touch, or how much they both wish September would stay far, far away.
