City Suit, Country Boy by Mia Terry

Advertising executive Kris Worth has carefully arranged his life according to his own specifications. He knows what it is to lose control, and will never let that happen again. But in the year since his best friend found love and moved to the country, he’s begun to notice a shortage of meaningful connections in his relationships.
Auto mechanic Billy Driscoll’s life is in free fall. His involuntary outing and a brutal beating at the hands of his brother have left him no alternative but to accept help in the form of an offer to move from the remote rural hamlet of Dungoon to urban Sydney.
When former roommate Jai asks Kris to take Billy in, the prospect of babysitting a damaged country boy is daunting, but he finds he can’t say no. Each of these men is in for some surprises as he discovers his assumptions about the other may have been wildly inaccurate. They manage to find common ground—steamy sex can work wonders in that regard— but will they be able to move beyond their histories and turn their combustible chemistry into a lasting relationship?
