Since the 5th book in the Safehold series came out, I thought I’d go ahead and nominate the first one. The series is about a remnant human population which was knocked back to a preindustrial level of technology and kept there by a manufactured religion. Almost 1000 years after the colony was founded, an android left by another faction within the group that established the colony wakes up and is working to free the people of Safehold from the constraints that were placed on them.
Not really sure what else to put here since this is the first time I’ve nominated anything for the book club.
