Brother's Best Friend Romance Books

He's been around her whole life — her brother's best friend, practically family. She was supposed to be off his radar. He was supposed to be off-limits. But some rules exist just to be broken, and some feelings refuse to stay buried no matter how long you try.

Kaci Rose's brother's best friend romances bring this irresistible forbidden dynamic into the mountains, where loyalty runs deep, proximity is unavoidable, and the man who was always supposed to be just a family friend turns out to be the one she can't live without.

  • Forbidden attraction built on years of history and longing
  • The delicious tension of wanting what you're not supposed to have
  • Protective, loyal mountain men caught between brotherhood and love
  • Slow-burn romance with explosive, deeply satisfying happily-ever-afters

For readers who love a romance where breaking the rules feels absolutely, completely right.
