The novel “Six Wakes” by Mur Lafferty was published for the first time in 2017.

When Maria Arena wakes up, she remembers the beginning of the journey of the starship Dormire but something went wrong because she discovers her previous clone, who shows visible signs of being much older than when the journey began and was killed. The other crew members turn out to be in the same situation except the captain, whose previous body is in a coma but still alive.

A check-up of the onboard systems shows that the IAN artificial intelligence is not working. The cloning systems have been sabotaged, meaning that records of the crew members’ memories are unavailable and it’s impossible to create new clones. There’s a saboteur on board but everything suggests that he must be a member of the crew, an easy conclusion to reach also because they’re all criminals.
