Because the author is being modest, I’d like to add a reply to Jack about Easter eggs in Gordon Korman’s works.

The biggest one I can think of offhand is the go-to alias “G. Gavin Gunhold.” That name appeared first (I think) in A Semester in the Life of a Garbage Bag (in which Gunhold was a poet and a major character, sort of). In other early books, “Gunhold” was a fictitious student, a marathon runner, a diploma earner, and the name painted on a warehouse. I remember being excited every time I found a new Gavin Gunhold when I was a kid reading those books for the first time.
