Great series

The Worst is a great series. I ordered them for my 3 year old granddaughter, and they’re her favorite. She has all except the newest one, which I will be ordering for her birthday.

This series is so worth reading to kids!
Format: Hardcover
Such a fun book in the series. Gilbert is back and having another fun (mildly sarcastic) adventure. Love reading these to my kids. They enjoy them and I find some humor in them.
