When Bear's Ma sprains her wrist and needs help moving her mother into a home, Bear is the first one to volunteer to come and help out for a couple of weeks to get the house in order. He's execting some time away from the club and some good quality family time. He ends up getting more than he bargained for when his mother decides to take one last trip with her mom and leaves him to clean out the house with the help of her neighbor who also happens to be a huge pain in the ass while also cute, clever and incredibly hot. Tempers flare and sparks fly in the fourth installment of The Rough Hearts Motorcycle Club. Harder Than Steel is the fourth book in The Rough Hearts Motorcycle Club but can be read as a standalone.
