Knot the Broseph by Liam Kingsley

Nyle’s done well for himself – at only twenty-six years old, he’s the prime alpha of the close-knit Howling Hills Pack, as well as the owner of the town’s hottest nightclub: Club Rumblefish. There’s just one thing missing: a mate. And when Nyle receives word that his best friend – and longtime crush – is returning home from his military service, his wolf can’t help but sit up and take notice.
Seph is glad to be home. He didn’t hate the military – but he was never able to keep himself completely invested. Part of his heart has always been back home in Howling Hills, with the alpha he left behind: Nyle. There’s only one problem – he and Nyle have never taken that final step from best friends to lovers.
When Seph’s heat hits him unexpectedly only hours after their reunion, neither man is prepared for the scorching fire that arises between them, and even though they agree to keep it casual, realizing that they are fated mates changes everything.
But fate can only provide a nudge in the right direction. Relationships take work – and if this couple can’t learn to trust each with their deepest feelings, they risk losing everything.
