Another fun title in this series!
Format: Hardcover
This book (and the other two in this series) are constantly checked out at my elementary school library! I love using these books to teach about opinion writing. The kids love the humor and illustrations! They’re great read-alouds too!

High quality
Format: Hardcover
The one that started it all! This book made it tradition to get a “the worst” (best) series for my brother for Christmas each year. Everyone loves it, highly recommend getting. Fun to read, great illustration, funny for everyone.

Family favorite series
Format: Hardcover
My daughter had a friend having a unicorn and dragon themed birthday party, so of course we picked up this one and Unicorns Are The Worst for the birthday girl. This series has been a big favorite in our household for over a year. My five year old loves them. The tone and humor are perfect for her age. We love seeing what complaints Gilbert has about each new mythical friend.
