The Hitman’s Omega Priest by A.M. Arthur

An omega priest goes on the run with a hitman who shouldn’t be alive.

Kensley Thorne lives the lonely, mundane life of an ordained priest, secured away from the wider world like most omega males. Sent to the abbey when he was fourteen, Kensley resents his boring life, and he resents King, his older half-brother who sent him there. He’s also never forgotten Bishop, his brother’s best friend, who’s ten years older than Kensley…even after he learns of Bishop’s violent death.
Bishop Anders has worked for King’s organization for more than half his life, and after a nearly-successful assassination attempt, Bishop goes undercover…guarding the grownup version of the teenager he’s never forgotten. When one of King’s enemies attempts to kidnap Kensley as leverage, Bishop intervenes and the pair goes into hiding.
Sparks fly the moment they touch, and they only burn brighter when Kensley realizes Bishop is his “dead” crush. Fourteen years of Kensley denying his sexuality fuels their newfound passion, and despite living in constant danger, neither man has ever been happier. But omega males are kept sequestered from the world for a reason, and King’s enemies aren’t the only ones who are after Kensley….
