In the wake of a shocking tragedy, Natalie Harper inherits her mother?s charming but financially strapped bookshop in San Francisco. She also becomes caretaker for her ailing grandfather Andrew. Natalie thinks it?s best to move him to an assisted living facility. To pay for it, she plans to close the bookstore and sell the derelict but valuable building on historic Perdita Street. There?s only one problem: Grandpa Andrew owns the building and refuses to sell. Natalie will do whatever it takes to make her grandfather?s final years happy. Besides, she loves the store. After she moves into the small studio apartment above the shop, Natalie carries out her grandfather?s request and hires contractor Peach Gallagher to do the necessary repairs. His young daughter, Dorothy, also becomes a regular at the store, and she and Natalie begin reading together while Peach works. To Natalie?s surprise, her sorrow begins to dissipate as her life becomes an unexpected journey of new connections and revelations, from unearthing artifacts hidden in the bookshop?s walls to discovering the truth about her family and her own heart.
