A Harrowing Account of Addiction, Recovery, and Relapse
Format: Hardcover
Greg Pizzoli’s The Watermelon Seed offers a deceptively simple yet profound exploration of addiction, recovery, and relapse. Through the crocodile’s obsessive love for watermelon, his panic upon swallowing a seed mirrors the fear and anxiety of losing control. The cycle of indulgence, dread, and inevitable return to the source of both pleasure and distress reflects the cyclical nature of addiction. Pizzoli’s playful illustrations mask a darker undercurrent: the crocodile knows watermelon may harm him — yet he cannot resist. A chillingly accurate portrait of the addictive mind, wrapped in the guise of a children’s story.

Cute but
Format: Hardcover
Caution that some children may be alarmed by the crocodile swallowing the watermelon seed. Know your audience. Otherwise a very cute, silly story that is great for a summer read or watermelon theme lesson.

A Special Education Treasure
Format: Board book
I bought this book with one student in mind. A third grade autistic, non verbal, girl with a love for books, animals and reflective surfaces (windows, puddles, utensils and mirrors to name a few). The bright, cheerful illustration was the immediate interest upon her first look. The engaging fun story kept her attention. The last page captivated her. What a complete joy to watch! She will now say "Wiggle" when she wants this book - several times a day. She follows along with her finger while I read. I do not read the last page. She does that all ON HER OWN! Did I mention non verbal?! I'm purchasing another as a Christmas surprise for her to have at home. I highly recommend this book as a fixture in the classroom for Special Education and Early Learning.
