We purchased this book for Rachel's birthday, and it arrived yesterday. Our middle daughter is a Rick Riordan fanatic, to put it mildly. FWIW, I've read the first five Percy Jackson books, and can recommend them. Riordan slips in some sly commentary about our times here and there, and it's a hoot.
Anyhoo. So she has her long-awaited tome, and I ask: "Do you like the book?"
Rachel: "Oh, definitely--and I was surprised by whose child Magnus Chase is, too!"
Me: "I guess you can say it Ragnaroks your world, then?"
Dale III, approvingly: "Oh, that's horrible, Dad."
