Friends: Snake and Lizard by Joy CrowleyElementary Fiction
Wen I first ordered this book, I went off the information provided that it was for "primary" readers. This is most certainly not the case. The book would be a great read-aloud for primary-aged children, in bits and chapters. But an independent reader couldn't tackle the book until elementary school. It's a fairly lengthy chapter book.
The stories inside deal with the friendship of Snake and Lizard, who live in a desert and have not-so-remarkable adventures, which is not to say the book is boring. However, what is remarkable to a couple of cold-blooded desert dwellers is old hat to humans who have seen more of the world. Their naiveté is charming and the stories are cute, filled with fun. Many of them have valuable, but not preachy, lessons about friendship, how to treat others, lying, exaggeration, etc.
I believe this is the second in a series, but you won't suffer from confusion if you start with this one first. Overall, a sweet and funny read.
