Welcome back to Assassins Anonymous, the only twelve-step group where joining can be deadly.

When Astrid, known in her assassin days as Azrael, stopped showing up to Assassins Anonymous, the group assumed her past had caught up with her. Only her sponsor Mark, formerly the deadliest killer in the world, holds out hope that she’s okay. Then, during a meeting, the group gets a sign, or rather, a pizza delivery. Is there another psychopath out there who actually likes olives on their pizza, or is Astrid trying to send Mark a message?

Meanwhile, Astrid wakes up in the cell of a black site prison, on a remote island. A doctor subjects her to mysterious experiments, plumbing the depths of her memory and looking for a vital clue from her past. She’ll do anything to escape, except…killing anyone. Hmm. Turns out it’s not easy to blow this joint without blowing anything, or anyone up.
