What Should I Read? The Brain Lair

The Brain Lair (Un-Boring List)
Taking recommendations for future reading. My book gaps are mysteries (middle grade and young adult), classics, scary (will only take suggestions for mg/ya), narrative nonfiction (mg/ya). All suggestions are welcome but books should be traditionally published and readily available. 1 recommendation per person. Check my Goodreads to make sure I haven't already read the book!
