What is a good casual book about coming of age?

Catcher in the Rye is an easy classic read. He cusses a lot.

That moment when you need to remember all that you read haha XD

Ahm maybe
Stardust
Arthurian Legend
The Metamorphosis (not really casual but you'll understand better if you know the author's story)

[i]Anne of Green Gables[/i], by Lucy Maud Montgomery fits your terms.

Not quite casual, yet a coming of age + social satire, is my own book, [i]BASIC NEEDS ETHICS[/i].

Happy reading!

"A Separate Peace", by John Knowles, if memory serves
"To Kill a Mockingbird"...

Are those in the vein you wish?

You could try The Chumscrubber. It’s a movie but still coming of age.
