In the richest installment yet of J. K. Rowling's seven-part story, Harry Potter confronts the unreliability of the very government of the magical world, and the impotence of the authorities at Hogwarts. Despite this (or perhaps because of it) Harry finds depth and strength in his friends, beyond what even he knew; boundless loyalty and unbearable sacrifice. Though thick runs the plot (as well as the spine), readers will race through these pages, and leave Hogwarts, like Harry, wishing only for the next train back.
