Cohesion by Aurora Crane

Five men, one love story.
None of them knew how many pieces they were missing until they all slotted into place.
Jericho thinks his life is complete, and that he doesn’t need anyone else. Quinn is sure he can never get back what he’s lost. Will wants to be a piece of someone’s heart, the hero of their story. Peyton fights his nightmares alone, struggling against the tide, his own dark thoughts an anchor. Sebastian’s hardened heart keeps him from letting anyone else in, too afraid to be hurt again.
Now real happiness, together, is within their grasp. Everything might be perfect if it weren’t for the man who wants all of their heads and won’t stop until he has them. It will take everything the five men have to reach for their happily ever after.
When the worst happens and their precarious foundation crumbles around them, is the love they weren’t prepared for going to be enough to keep them together… and alive?
