Stryke First by Sandrine Gasq-Dion

This book is part of a series. It contains homosexual relations, violence and coarse language. It is preceded by Falcon’s Fox.
Rebel Stryker has had to fight to survive from the moment he was born to a heroin-addicted mother. Raised by his grandparents, his only mission in life was to succeed where his mother had failed. Now, he and his childhood best friends tour the world as a famous heavy metal band. Like any rags-to-riches young man, Rebel definitely enjoys the perks of being in the limelight.
But now something has changed.
Rebel never wanted to fall in love, shying away from relationships and relishing his ‘no worries’ rock-star persona. But there’s something about the band’s new manager that catches Rebel’s eye. Despite fighting it with everything he has, Rebel finds himself succumbing to man’s quiet ways. It doesn’t hurt that the guy loves Rebel’s grandpa — the one relationship that means the world to him.
Staying true to his name, Rebel fights against the tide of attraction drawing him in. But it’s only a matter of time before love finally strikes.
Stan Jackson is hiding a secret. A Very Big Secret. One he prays will never come to light, especially since life is pretty good now. He finally has a good job, and he considers the people around him friends — even if they don’t see him the same way. All he’s ever wanted in life is to blend in, not make waves, and move on through. Now, as the manager of the internationally famous Skull Blasters rock band, he is put squarely into bassist Rebel Stryker’s orbit. He spends a lot of time with Rebel’s grandfather, which is not only fun, but rewarding. Another big benefit is that Stan gets to see Rebel all the time. When his past catches up to him, Stan learns that he isn’t just the Skull Blasters’ manager.
