'The Handmaid's Tale' was Amazon's most-read fiction book of the summer - here are the others

As the penultimate season of "Game of Thrones" aired this summer, it's no wonder that Martin's "A Game of Thrones" was popular.

While the show is now off-book, it makes sense that fans would want to return to the source material. Perhaps readers were looking for clues that indicate how the final season of "Game of Thrones" will end.

The first novel in the "Harry Potter" series, "Harry Potter and the Sorcerer's Stone," was one of the most read books this summer — 20 years after its release.

Daniel Silva's "House of Spies" quickly gained popularity this summer, shortly after it was released. The novel follows Gabriel Allon on his search for a the world's deadliest terrorist and ISIS mastermind.

The movie "It" is already being dubbed the first big hit of the fall movie season, and it seems as though Stephen King fans were gearing up for the film this summer by re-reading his lengthy (1,184 page!) novel "It."
