Holy crap these books are good. J.K. Rowling's ability to grow with her audience, to darken the themes and write a great story that young adults and older young adults can both enjoy is uncanny. It was truly magical reading these books, and the wonderful journey came to an excellent close. Though it did meander a bit, it's all the same in the end. Rowling's themes of fear and power are so profound and timely, these books are classics and highly recommended.
I'd argue with anyone that says different.
