Instantly lovable YA retelling of Arthurian legend

I love a good classic retelling with a twist, and this does not disappoint! Immediately we get a good glimpse into characters full of humor, attitude, and troubles. I already feel like I'm a part of this believable world. I want to be friends with Arthur and Lancelot. I want to learn magic with Emry. We get Arthur pulling the sword out of the stone so early on, I can't wait to see what the rest of the book has in store!
