Mr. Penumbra's 24-Hour Bookstore

I read Mr. Penumbra's 24-Hour Bookstore for my summer reading. On a scale of one to ten, I would give this novel a five. It was not  boring and it managed to keep me interested but it didn't entirely spark a fascination as some novels have done for me.

Clay Jannon was laid off from his work at New York City's NewBagel. He moves to San Francisco and finds work at Mr. Penumbra's 24-Hour Bookstore, a mysterious, hole-in-the-wall library with unquestionably creepy visitors. Jannon goes on a whirlwind adventure to figure out the secrets behind this mysterious cult and what lies beneath it. The theme of this novel is the ever-changing world of no only social media, but electronics themselves.
