Six Wakes by Mur Lafferty

 Suspense. Murder. Science fiction. Mystery.

There's a lot to like about this interstellar mystery. It's unique. It's well-written and it reads fast. It has six interesting characters and an intriguing premise. And it's set in space. But I have to admit, I'm finding it a little hard to summarize. So I'm going to cheat and quote from the blurb on Goodreads instead.

"A space adventure set on a lone ship where the clones of a murdered crew must find their murderer -- before they kill again.

It was not common to awaken in a cloning vat streaked with drying blood. At least, Maria Arena had never experienced it. She had no memory of how she died. That was also new; before, when she had awakened as a new clone, her first memory was of how she died.

Maria's vat was in the front of six vats, each one holding the clone of a crew member of the starship Dormire... And Maria wasn't the only one to die recently."

Because the ship's AI memory logs have been wiped, and none of the six cloned crew members have retained any recent memories, you don't know who to trust. Any one of them could have committed the murders and sabotaged the ship's computer. There's the captain, the pilot, the doctor, the tech guy, the security guy, and Maria, jill-of-all-trades. Each has a criminal past and each knows their own piece of the puzzle. But none feel they can trust any of the others. 

I always enjoy reading these kinds of locked-room mysteries (or locked-ship mystery in this case), and I found Six Wakes to be both compelling and entertaining. I especially liked all the clone technology, with its complicated moral and ethical issues, and the six clones with their past lives, their memories, secrets and altered mindmaps. If you like character-driven mysteries, especially ones set in space, this is a really good one. 

Happy Reading!
