Why we recommend it

A grumpy biker and a curvy nurse stuck in close quarters make for a warm, lower-heat-danger MC romance with plenty of swoon. Forced proximity does the heavy lifting as a gruff alpha softens for the woman patching him up, body and ego alike. Readers who love size-difference tenderness, protective possessiveness, and a hero who hides his marshmallow center under tattoos and attitude will find this one cozy and satisfying.
