Collection: Sei Assassin Thrillers

They stole her daughter. They messed with the wrong mother.

Sei is one of the world’s deadliest assassins—until she vanishes. Years later, she resurfaces with one goal: find the daughter she thought was dead. Her search takes her across the globe, leaving a trail of bodies behind. She’s not on a mission—she’s on a warpath.

Readers know her as the Assassin Mama—and they’re not wrong.

"Hutchinson has given us an amazingly strong character in Sei" — Blog Critics
