Four generations—or at least sixty years—have passed on Isis since The Keeper of the Isis Light. For the colony that mutually rejected Olwen, the Keeper, and her AI Guardian years ago, however, things have not been going all that well. The colony is still trapped in the same valley, and, probably because this is a Monica Hughes book, is starting to run short on food.
Far worse, apparently in reaction to the events in the previous book, the colonists have deliberately gone backwards. They’ve discarded technology (including rather important elements like water gauges to track just how high the lake is getting), turned Guardian and Olwen into mythological figures to be worshipped instead of approached for technological assistance, discarded literacy, and added elements like “taboo” and sexism. I knew rejecting Olwen was going to be a bad thing, but this bad? Harsh.
See what your meddling led to, Guardian of Isis?
