Navigating Early by Clare Vanderpool
Another amazing book from Clare Vanderpool, whose first published book, Moon Over Manifest, won the Newbery Medal. In her second book, it is 1945 and Jack has begun boarding school in Maine after losing his mother and being moved from his native Kansas to Maine by his Navy father. Jack meets an odd boy at the school named Early Auden. Early is a mathematical genius, with a special interest in the number pi. He sees the number as a character in a story that he relates to Jack. Then he and Jack go on a quest along the Appalachian Trail, where their adventures seem to parallel the adventures of the characters in the pi story. This is a wonderful book, filled with a magical journey with remarkable characters and adventures.
