Terrible writing and progression of plot, I gave up 45 minutes in. I couldn't get into the book either, so maybe I shouldn't have been surprised. My suspension of disbelief just never kicked in. I believed in the monsters from A Quiet Place and the entity in Bird Box, but the swarms we're given here only came off absurd to me. Add in cheap moves like killing a baby and a dog for dramatic effect, and I'm glad I never got as far as the cult subplot. It wouldn't have improved things.
