Trudell Becket, known to her friends as Tru, finds herself in a bind when her library in lovely Cypress, South Carolina, is turned into a state-of-the-art bookless "technological center". A library with no books breaks Tru's book-loving heart so she decides to rescue hundreds of beloved tomes slated for the town dump. Under the cover of darkness, Tru, along with her best friends - coffee shop owner Tori Green and mysterious best-selling author Flossie Finnegan-Baker - set up a secret bookroom in the library's basement and prepare to open it to their most loyal, trustworthy patrons.

But as Tru and her crew are putting the finishing touches on their new book room, the town manager, who was behind the big push for the library's transformation, is crushed by an overturned shelf of DVDs. Tru becomes the prime suspect as she hadn't hid the fact that she hated having all of those wonderful books replaced by tablets and computers.

Tru knows she's in a heap of trouble, and it doesn't help that the officer in charge of the case is her old crush from high school, who broke her teenaged heart. To keep herself out of jail and her beloved bookroom up and running, Tru - with the help of Tori, Flossie, and a brown tabby stray cat named Dewey Decimal - decides to investigate.
