Of a 1000 books:

A Day in the Life of Marlon Bundo by Jill Twiss and E.G. Keller at 4.64. This is the only kids book I have on here and I read it before sending to my niece lol

Actual book is A Court of Mist and Fury by Sarah J Maas at 4.62 which is pretty shocking even if I enjoyed it.

The Almost Moon by Alice Sebold at 2.7 (!) which feels harsh but I don't remember a thing about it to defend it so...
