The Boyfriend Algorithm

by Kendall Ryan

A sexy, feel-good rom-com from New York Times bestselling author Kendall Ryan about the world's most advanced boyfriend—and the one woman he never saw coming.

Ruby Hart’s life is falling apart.

Her bakery is barely staying afloat, her ex just got engaged, and her mother won’t stop sending her dating profiles. The last thing Ruby needs is another problem.

Then a man crashes through her window.
A very confused man.
A very handsome man.
A very naked man.

He has no belly button, no memories, and he might not be entirely... human. According to the control panel hidden beneath his ribs, he’s one of the decommissioned companion synths—obsolete artificial humans with superior intelligence, questionable social skills, and absolutely no understanding of personal boundaries.

Aiden doesn’t understand sarcasm, doesn’t know why he’s not allowed to watch Ruby sleep, and can’t explain why his systems reroute every time she walks into a room. But he’s willing to learn—especially the part where he pretends to be her boyfriend for one weekend.

One wedding. One fake relationship. One synthetic man who’s becoming a little less machine every day. Protective. Possessive. Loyal. And increasingly impossible to resist.

The Boyfriend Algorithm is a funny, heartfelt rom-com with a devoted artificial hero, very real chemistry, found family, and a love story worth rewriting the rules for.

✨ Fake dating
✨ He falls first (and hard)
✨ Socially clueless hero
✨ Learning to be human
✨ Obsessed with her
✨ Forced proximity
✨ Spice, banter, and heart
