Harry Potter Series by J.K. Rowling No book series roundup would be complete without everyone's favourite boy wizard. J.K. Rowling's Harry Potter and the Sorcerer's Stone welcomes readers (and Harry himself) to the fantastical world of Hogwarts School of Witchcraft and Wizardry — as well as the dark magic that lurks outside of its walls. This magical seven-book series should seriously be required reading for everyone. Image Source: amazon.com
