Challenging, but also fun, active learning review exercise based on the novel by Patrick Ness.
There are 36 clues. Words used in the puzzle are primarily the names of characters and locations. I've also included some key terms (Noise, Ask, Answer). I've written the clues with as much detail as possible, so that students are learning (or revising) as they work on this activity. In this way, it's not just a time filler. This is a summary quiz, designed to be used after reading the novel.
There is a word bank to assist students. You could redact this to make it more difficult. In this case, I would use as an open book quiz. Download the solution (the preview file) to see the words used in the puzzle.
