Perfect for you if...

You love slow-burn romance where physical chemistry builds alongside emotional trust, especially when one partner is deliberately closed off.
You're drawn to contemporary romance with darker undertones, where comfort and danger get tangled together.
You enjoy brother's best friend tropes that actually feel earned, where resistance crumbles because of real circumstances, not just proximity.

Maybe not for you if...

You prefer lightish romance without domestic peril or genuine suspense woven into the love story.
You want your grumpy love interests to soften quickly through banter rather than through witnessing vulnerability.
You dislike cliffhangers or unresolved plot threads that demand you read the next book in the series.

About this book

Anson Hunt is the new contractor working on the narrator's house—and also her brother's best friend. He is grumpy, rude, and prefers solitude, resistant to her attempts at friendliness. When the narrator's world falls apart, Anson becomes her protector, catching her as she falls. As a series of accidents begin affecting her life, he steps in to keep her safe. Their proximity sparks attraction that quickly intensifies between them. However, Anson carries secrets with serious consequences. When these secrets come to light, both of them will face significant fallout.
