By My Own Betrayal – Young Adult Novel + Series

To live is Christ. To die is much more likely.

Raised as a skilled assassin, the young and ambitious Sadie Black knows nothing else; her only way to live is for someone to die. Doing otherwise would betray her sole support network and leave her at the wrong end of a gun—which is exactly where Sadie has landed herself.

Abandoning the life of a hired killer for a new life in Christ, Sadie must work with a self-reliant FBI agent and his cryptic superior to secure her freedom before a vengeful family can steal her back to the career she’s desperately running from. Or they execute something a bit more…fatal.

Filled with sarcasm and intrigue, this contemporary faith-based novel proves itself as a must-read for adventure-seeking teens and new adults.

dead and buried – Book 2 of the By My Own Betrayal series

Her family thinks she’s dead. If she’s not careful, she will be.

A young criminal informant died in the hospital after a disastrous encounter with a ring of hitmen; at least, that’s the story on FBI records. While authorities search for the fugitive assassins—the deceased’s own kin—Sadie emerges from the hospital with a new identity, scars that stretch far beneath the surface, and a single-minded resolve: she will share her faith in Jesus Christ with her beloved family. With an agonizing eternity hanging on the inevitable demise of each parent and sibling, Sadie must rely on her skills and insights as a trained killer-for-hire and find them before they disappear forever.

When a coded message linked to her childhood home surfaces, Agent James Way approaches Sadie to help decipher it. She accepts his offer, sacrificing her ability to pursue her family off the FBI radar and assuming a ‘normal’ life in exchange for access to confidential intel.

But putting her murderous past behind her isn’t as easy as changing her name; neither a ‘normal’ life nor her own presumed death can sever the ties to her blood-soaked history, especially the ties that insist she should have never left the hospital in the first place.
