Full Night’s Sleep by Kiki Burrelli

Grayson Davenwood is an alpha who has spent his life in the field of omega medical research and despite the numerous drugs his company as created that have made omega life easier, it is never enough to erase the guilt he feels for failing to protect his best friend and true mate almost twenty years ago.
With the prospect of starting a family stolen from him, Grayson cares only about his business. He’s an alpha with a one track mind until Lochlan Varner, an omega in trouble, pushes him off the rails.

Lochlan knows what it is like to be helpless and has sworn to never return to that state. Raising his son alone, while taking in wayward omegas and acting as president of the covert organization, the Alliance for Omega Equality, he knows what it is like to end each day exhausted. Taking on a potentially dangerous mission to bring down the country’s largest drug company is simply another step he must take to ensure that one day, omegas will be treated with respect. When Lochlan meets Grayson, he wants to believe he’s just another overbearing alpha that thinks his gender entitles him to respect and obedience.

It doesn’t take long for Lochlan to realize Grayson is different from any other alpha he has met, especially his abusive ex whom Lochlan has not seen in five years but who still searches for him and his son.
Grayson can’t deny his attraction to the omega. His chance at giving his mate his knot may be gone, but that doesn’t mean Grayson can’t protect Lochlan. Except, as they spend time together, Grayson begins to realize that they have a bond that is beyond friendship. Lochlan is his and Grayson will move mountains to convince him.
