A fun mystery around a generation ship that uses cloning to get to where they want to go with a minimal crew. How immortal clones who keep moving to fresh bodies will be different from normal humans and why they haven't taken over the world is the premise of this intricate murder mystery. Because the crew is murdered and they better figure out who murdered them.

This was quite a lot more fun than I anticipated. I am not a mystery expert so someone more versed in the genre might have seen things coming earlier for me it was just the right amount of mystery versus technology and world building from the SF portion of the book.

I like the fresh (to me?) take on how clones are a different species from humans altogether.
