Book – “What do you seek in these shelves?” What recently unemployed graphic designer Clay Jannon sought was employment. His quest was successful at Mr. Penumbra’s 24-Hour Bookstore; a place with bookshelves and ladders extending up three stories, and a collection of curious books that are never bought, but are “checked-out” by eccentric individuals. Clay calls upon his friends to assist him with investigating mysteries which extend far beyond the walls of the enigmatic store. This thought-provoking tale includes puzzles that revolve around technology as antiquated as the printing press and as cutting edge as Google wizardry. The humorous writing and optimistic tone make this novel a rejuvenating read. Appropriately, this book offers a surprise if the reader turns out the light. The audiobook does not offer that perk, but the narrator Ari Filakos delivers the likable Clay’s inner monologues and quirky humor so well that I went back and listened to some key sections to hear his moving delivery of them.
