The Best Friend Effect

By Carrie Costello

Falling for your brother's best friend? That was never part of the vacation plan.

Sophie Parker is overdue for a break. Between lesson plans and laundry piles, she barely remembers what fun feels like. When her brother invites her on a week-long luxury cruise, she agrees-because sunshine and cocktails beat grading papers any day.

What she doesn't expect? Colin Bryant.

Her brother's best friend.
Her longtime nemesis.
The man who has made teasing her an art form since they were kids.

Colin has always been infuriatingly charming and way too sure of himself, but stuck together on a ship in the middle of the ocean, their usual back-and-forth shifts into something neither of them can ignore. Suddenly, his teasing feels more like flirting. His smiles linger a little too long. And when their friends conveniently disappear, leaving them alone together, Sophie starts seeing Colin in an entirely new light.

One vacation. One unexpected connection. One very inconvenient attraction.

Sophie swore she'd never fall for her brother's best friend. But under the Caribbean sun, where the rules don't seem to matter, she's beginning to wonder...

What if the best friend effect has been working against her all along?

A swoon-worthy, slow-burn romance with undeniable chemistry, witty banter, and just the right amount of steam. Perfect for fans of forced proximity, brother's best friend romance, and vacation flings that just might turn into something more.
