When tragedy strikes the Bryce Beach Public Library, the choice is clear for librarian Sunshine Baker: solve the mystery or lose her job. Despite having no prior sleuthing experience, Sunshine feels uniquely qualified due to her ninja YA librarian skills and all those Nancy Drew books she read as a kid. With the help of children’s librarian Molly Simmons and cataloguer Evangeline Dupree, Sunshine and her colleagues scour Bryce Beach for suspects, clues, and the stolen treasure. Can she and her squad recover the proceeds from the library’s annual fundraising gala and Bryce Beach’s most priceless historical artifact, the Bible with the town’s founding fathers’ signatures? But here’s the most vexing question of all: could one of Sunshine’s colleagues be a backstabbing traitor out to destroy the library?
