The final book of the trilogy comes to a satisfying conclusion. More magical quests on Earth and on Fillory, with reappearance of some characters from books one and two. About 12 years have passed since book 1 and the consequences of doing magic and experiencing great magic has changed the magicians, bringing a world-weary maturity. This series is wonderfully imaginative. However, the 3 books need to be read sequentially; none are stand-alone stories.
