Hard Tail by JL Merrow

Finding love can be a bumpy ride
With his job and his marriage dead in a ditch, Tim Knight doesn’t take much persuading to leave London for the greener fields of Southampton and look after his injured brother’s mountain bike shop. But Tim’s a fish out of water in this brave new world of outdoor sports and technical jargon—not to mention struggling with the realisation he can no longer deny his sexuality, at least to himself.
The reason? Matt Berridge, his brother’s bike mechanic. Fit, tanned and an adorable klutz, Matt takes a tumble the day they meet and falls straight into Tim’s heart. There’s only one problem: Matt’s boyfriend, who Tim’s convinced is abusing him, despite the stories Matt comes up with to explain away the bruises.

A black belt in karate, Tim’s no pushover when it comes to physical confrontation. But he’ll need to step his courage up a gear if he’s ever going to come out, be himself—and save the man he’s coming to love.
