It's Zinnia Gray's twenty-first birthday, which is extra-special because it's the last birthday she'll ever have. When she was young, an industrial accident left Zinnia with a rare condition. Not much is known about her illness, just that no one has lived past twenty-one. Her best friend Charm is intent on making Zinnia's last birthday special with a full sleeping beauty experience, complete with a tower and a spinning wheel. But when Zinnia pricks her finger, something strange and unexpected happens, and she finds herself falling through worlds, with another sleeping beauty, just as desperate to escape her fate.

In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety. But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern. On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied ‘droid — a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.” Scornful of humans, all it really wants is to be left alone long enough to figure out who it is. But when a neighboring mission goes dark, it's up to the scientists and their Murderbot to get to the truth.
