When author Harlow Keaton needs a place to unwind with her daughter and write her book, her grumpy childhood best friend Ian Wilder offers up his spare bedroom, and the line between best friends and something more starts to get blurry in this emotional small town romance for readers of Elsie Silver, Lauren Asher, Laura Pavlov, and Corinne Michaels.

Sweet, spicy romance that will tug on every single heart string. — Melanie Harlow, USA Today bestselling author

Imagine this: an author with a raging case of writer's block finds an unexpected source of inspiration in her grumpy, gorgeous new roommate. Sounds amazing, right? Except that new roommate is my childhood best friend. And Ian Wilder has been off-limits since I was five.

It's been over a decade since I've seen him, but when I return to my hometown after years away, Ian's exactly the man I remembered. The same guy who gave me his coat on a playground when we were kids and promised he'd take care of me forever. I need a quiet place to work with this deadline looming. I need a place where my daughter can unwind. Enter Ian with an offer I can't refuse: his spare bedroom.

It's an easy yes. Except now the problem is I can't stop thinking about him, and these thoughts? They're wandering out of the friend zone. I keep imagining very creative ways to rip off his clothes. And Ian starts giving me looks of his own, the kind that make my heart race.

One night, we cross a line we can't uncross. The lines have blurred, and our friendship is hanging by a thread.

Imagine this: a woman falling for her best friend. And she has no idea if he feels the same.

Promise Me This is a slow burn, friends to lovers, forced proximity romance mixed with rugged small-town charm and heartwarming family shenanigans. Welcome to the Wilder family!
