Last year, Martha Wells published All Systems Red, the first installment of a Tor.com novella series called The Murderbot Diaries, which follows the adventures of the titular android as it is pulled into various adventures while traversing inhabited space. Wells earned considerable acclaim for All Systems Red: it became a New York Times bestseller, and earned her the Hugo and Nebula Awards earlier this year. Since then, she’s published three new installments concerning the adventures of the titular android — the last one came out earlier this month. Individually, they’re an intriguing set of adventures. But collectively, they form a larger story about a machine coming to understand what it means to be human.
