What if the only way you could save your own life was to kill yourself?

Someone is trying to kill Sophie Rippetoe, and she has no place to hide. But Sophie has a unique option. Her husband designed and built a duplicator machine to make exact copies of complicated and sophisticated machine parts. She knows how the duplicator works.

Will it work for people? No one knows.

There’s just one problem: the duplication process destroys the original. The only thing Sophie knows for sure is that trying to make copies of herself will end up killing her.

Sophie isn’t sure who’s trying to kill her or why – but she has her suspicions and has gathered some evidence. She has created a trail of clues, hopeful that at least one of the Sophies she creates will figure out who the killer is in time to save herself.
