Isla and the Imaginary Iguana By: Nancy Jasin Ensley I'm Isla, and in this book you'll meet my Iguana, Ivan. Well, my grandma says Ivan is a stuffed animal, not a real Iguana. It's okay though. Ivan is softer and cuddlier than the one at the zoo. But I still like going to the zoo and other places with my family because I can learn new words. I have a list of words that gets longer every day! If you like to learn and explore too, I hope you'll join me on all my little adventures.
