Emma Justice is friends with the local librarian and brings her extra flowers once a week. On a hot July morning, when people are gathered outside the closed library past opening time, Emma calls the police. The librarian's body is found in the building and beside the body is a pink and white bleeding heart plant.

Tess Carranza was a lovely person dedicated to children and patrons of the library in Lutz, Texas. Tess recently confided to Emma about her fear someone was using the library to gather information to commit crimes. Emma didn't get the entire story from Tess before her death, but now she's determined to stop the crime and catch Tess's killer.
