The more I listen to this series the more I like it. Each of the stories in the series build from the one before while managing to be unique so that as soon as you finish one "day" you can't wait to find out what he has in store for the next one. And while remaining imaginative and creative he also slyly borrows imagery (religious, mythological, historical) from so many sources that some interesting little tidbit pops up with each book or chapter.
In this installment Arthur is drafted into the Army of the Architect, gets washed between the ears and learns some combat skills. Would have liked to spend more time in the Maze but it was a solid story and we get to meet the Piper.
