Brendon Lowell loves love. It's why he created a dating app to help people find their one true pairing and why he's convinced "the one" is out there—even if he hasn't met them yet. Or... has he?

When his sister's best friend, Annie, unexpectedly turns up in Seattle, Brendon jumps at the chance to spend time with her. He's crushed on Annie since they were kids, and now the stars have finally aligned, putting them in the same city at the same time.

Annie is in town for a spontaneous trip before moving across the globe. She's not looking for love, especially not with her best friend's brother. She remembers Brendon as a sweet, dorky kid. But the 6-foot-4 man who shows up at her door is a certified Hot Nerd, and Annie can't help but take notice.

Getting involved would be a terrible idea—her stay is temporary, and he wants forever. But when Brendon learns Annie has given up on dating, he's determined to prove that romance isn't dead. Taking cues from his favorite rom-coms, he plans to woo her with elaborate dates straight out of Nora Ephron's playbook.

The clock is ticking on Annie's time in Seattle, and Brendon is starting to realize that romance isn't just flowers and chocolate. Will his grand gestures be enough to make Annie stay? Or will they both discover that real love doesn't have to be perfect—it just has to be true?
