A love letter to libraries. A puzzle for the ages. A fight for the future.

A stolen book. A cryptic note. Retired reporter Marvin MickleThwait knows something's wrong -- and librarian Gloria Thanh is his only hope.

Their search plunges them into a long-forgotten part of the library's underground stacks, where they discover a code hidden behind several spurious call numbers. Each clue pulls them deeper into a conspiracy that threatens not just the library, but their growing feelings for each other.

Someone wants this library closed. Permanently. And Marvin and Gloria stand in the way.

The stakes are higher than they imagined: if the library falls, other public institutions will follow. Two unlikely detectives. One impossible puzzle. And a race against time to crack the code that will keep the library doors open.

Perfect for book-loving fans of intricate mysteries and clever code-cracking.
