Jayson by Charissa Gracyk

This grumpy, single dad isn’t prepared for his new neighbor’s sunshine. Or her secret.

Single fatherJayson Knight fully expects to die in his recliner, a grumpy, lonely, old man. Ever since his daughter moved out, the house has felt too empty, and he doesn’t know what to do with himself. Unsure how to get back into the dating scene, he figures his options are limited, so why bother?
Until his new neighbor comes gliding into his life like a breath of fresh air, flashing her sunny smile and sweeping away the gloom.

Sabrina Ross is more than merely curious about the silver fox next door. She’s an undercover FBI agent sent to discover if the former Army Ranger and his friends are responsible for murdering a mafia kingpin.
Despite their immediate, all-consuming attraction, Sabrina has a job to do. But she quickly discovers everything is not so cut and dried. And her empty-nester neighbor is harboring secrets better left buried.

When Jayson’s daughter is kidnapped, Sabrina chooses to help the distraught father and jumps into danger. But then the tables turn, and she suddenly finds herself in the crosshairs.
Now Sabrina is trapped in a mobster’s lair, and time is running out fast. With the Motley Crew at his side, Jayson will stop at nothing to get Sabrina back…because losing the woman he can’t live without isn’t an option.

**Each book in the All Guts, No Glory series can be read as a standalone. Expect action, plenty of silver fox heroes, mature heroines and an HEA.
