Sworn Oath by Shea Balik

Long ago, Karsyn Vogt had accepted he wasn’t destined to have the family he’d always imagined. After losing the Omega he’d sworn to protect, he’d thrown himself into solving cold cases with the Hartland PD. But fate had a way of making the impossible possible once again when he met Jonah Klein. Despite their twenty year age difference, Karsyn was captivated by the Omega. He just wasn’t sure he deserved a second chance.
Jonah Klein was a survivor. After a group of Alphas had tried to kill him, he’d come back stronger and willing to fight for what he believed in. He just hadn’t expected he’d have to stand up to the man who could be his future.
If Karsyn and Jonah hope to find their happily ever after they must put aside their pasts and forge ahead to build a life together. But there are other forces besides the past that might get in their way. Vigilantes continue to create chaos all around them, as they attempt to right the wrong of murdered Omegas, who were forgotten by the very people who were supposed to protect them.
