Reactant: Chain Reaction

Jericho Rowlands spent most of his life living under different names, doing the dirty work required to keep Sydney safe. His time as Warren Boiler had put him on a collision course with Sebastian—the lawyer who kept him out of jail—and also brings him into contact with the three men who are such an important part of Sebastian's life. Jericho is only supposed to be keeping Sebastian alive; that's easier said than done when chemistry like he's never felt before flares between him and all four men.
Quinn, Peyton, Will, and Sebastian have the weight of history and mistakes and missed opportunities between all of them, making an already-complicated situation harder. None of them can deny the magnetic pull holding them together as they try to muddle through what their new normal will look like. Jericho isn't supposed to be part of it, but they can't ignore their instant connection.
The past has led them to where they are, but the threats of the present could end any chance for a future together. Sebastian and "Warren's" names are on a list, and everyone else on it is dying one by one. Quinn is racing against the clock, trying to figure out who's gunning for them from the shadows. Quinn and Will are standing on one side of the law, Peyton and Jericho hold the other, but even that might not be enough to keep Sebastian out of the crosshairs.
