I enjoyed Tuck Everlasting as a preteen, and I picked it up again because I realized one of my manuscripts has a few similar plot elements.
I’d forgotten how excellently written it was. If you struggle with creating a sense of place (a.k.a. filling in that white void around your characters with sensory details), this is a great book to read. And re-read.
I recommend Tuck Everlasting to all ages. I also recommend reading it out loud.
