Isaac at the school fete: I'll Give You the Sun
Nelson's 2014 novel about twins Noah and Jude, told by him at 13 and her at 16, with art and grief and first love in both halves. It won the Printz Award. Two halves of a story that only make sense together, which is the season-three finale in a sentence.
