I hear you! The themes of YA fiction can burn even deeper than adult fiction, because everything these characters feel is so raw and immediate. We need some levity after all that teen angst, right? Ok, here we go:
Spud, by John Van de Ruit--A young boy heads off to his first year in boarding school during South Africa's Apartheid. Hilarious high-jinks ensue, but the book is grounded with the emotional weight of coming-of-age.
Going Bovine, by Libba Bray. A kid realizes he has Mad Cow Disease and sets out on a delirious, hallucination-feuled, Quixotic quest.
Amy and Roger's Epic Detour, by Morgan Matson. When Amy's father dies, her family disintegrates: her mother heads off to a new job across the country, her brother to a clinic to detox, while Amy is left in California to finish her school year. Her mother has arranged for the son of a family friend to help Amy drive their car to Connecticut and this is where her life takes a wonderful detour. Warm, funny with very realistic characters, this is a fine read.
The Wednesday Wars--While it's technically low-YA geared toward middle readers, it's so smart and funny. Taking place during the Vietnam War era, a young boy earns his chops by reading Shakespeare with a teacher who hates him.
ANYTHING by John Green. My favorite is Paper Towns. It's about a nerdy kid, Q, who's always been in love with his next door neighbor--a wild child with a tough family. When she disappears, Q feels as though she's left him clues to track her down. It's a fantastic coming of age/love/buddy roadtrip story.
I mention this next one with a disclaimer: while there are some really heavy aspects to this story (some issues that crop up on your do not pass list), it is so worth the read. Jasper Jones, by Craig Silvey has been compared to To Kill a Mockingbird, and for good reason. In the 60s in a small town in Australia, our young narrator Charlie is recruited to help solve a mystery by the town's bad-boy Jasper Jones. The story is at times chilling, hilarious and thought-provoking.
I hope this gets you started! I'm always happy to add more.
