Silver Daddy by Liam Kingsley

He’s got the hots for his best friend’s dad …

Kiefer has been crushing on Greer since he was a teenager, never imagining anything could happen between them. Then one night changes everything. Now the older alpha is all he can think about and things between them are heating up. But Kiefer’s best friend, Jaxon, doesn’t want to see his father hurt, and Kiefer will need to stand strong if he’s going to keep his place at his mate’s side.
Greer has lost it all before, can he risk his heart again?
A lifetime ago, Greer lost his wife and young child. Since then, he’s sealed off his heart, unwilling to let it be torn out a second time. But when he scents that Kiefer is his fated mate, Greer knows there’s no fighting the bond between them. A second chance at love is more than Greer ever dreamed of, but a second chance at fatherhood has all of his protective instincts screaming to shield his mate and their unborn child from harm.
Greer’s zealous protection and Jaxon’s resentment might be too much for Kiefer to handle. He loves his mate and the life they could have together, but he refuses to be the reason the pack is torn apart. Can he and Greer find a way to navigate both the complicated pack and family dynamics, or is their fated bond already doomed to break?
