I am a huge fan of Peter Brown- author and children's book illustrator. Peter illustrated a new book coming out later this month called Creepy Carrots! written by Aaron Reynolds. If you haven't heard about it, here is a video called the creepy carrots zone. It was really cool to see Peter's illustration process. I can't wait to get my copy of the book! You should also check out Peter's books, "Children Make Terrible Pets" and "You Will Be My Friend!"- two of my favorites.
Another book my family really likes is called Big Plans by Bob Shea and illustrated by Lane Smith. We laughed the entire time we were reading this book - I highly recommend checking it out :)
