Three highly rated fantasy book series are "The Lord of the Rings," "A Game of Thrones" and "Harry Potter." Other recommended works include "Jonathan Strange and Mr. Norrell" by Susanna Clarke, "The Princess Bride" by William Goldman, "The Chronicles of Narnia" by C.S. Lewis and novels by Neil Gaiman.
Written by J.R.R. Tolkien, "The Fellowship of the Ring" - the first book in "The Lord of the Rings" trilogy - follows the adventures of Frodo, a young hobbit who embarks on a journey in a world filled with elves, dwarfs and wizards. Frodo's quest continues in the second and third books of the series, "The Two Towers" and the "The Return of the King."
"A Game of Thrones" by George R. R. Martin is the first novel in the series "A Song of Ice and Fire." Though it contains quite a bit of violence, this series has a complex story line with well-developed characters, plot twists and cliffhangers. As of 2015, this popular book series has inspired a highly acclaimed television series of the same name that airs on HBO.
Written by J.K. Rowling, the "Harry Potter" series, though originally intended for a younger audience, has been recommended by readers of all ages.
