Query: Ethereal

I could describe this book as science or history, but I think I'll go with poetry. It's the sort of thing you'd read when you feel like your life hasn't contained enough appreciation for the sublime. It's wicked interesting, but the stuff you learn along the way is more of a substrate on which Pollan creates an expressive work worth admiring for its own beauty. Can't recommend enough.
