Honestly, "Weird" was just so fun. Even though I first read it in middle school, probably 15 years ago, it still brings a smile to my face!
The blurb does say it all, and I haven't much to add. But it was just a delight, how everything came together for the last moment, how no character was put to waste and felt well explored, how no thread was left hanging. The ending? BAM! Didn't see it coming. It was really funny, and I wouldn't mind rereading it as a young adult.
Edit: Damn! Have been looking for this book like 10 years on now. Sooo good. It made me laugh so hard! Unfortunately think it's been lost to time, no idea where I put it. Must remember to re-order sometime.
