Gloria Gardner has finally committed to renovating the oldest section of her beloved greenhouse—the original 1920s structure her grandfather built with his own hands. But when the construction crew discovers a leather-bound diary hidden inside a hollow cedar beam, Gloria finds herself holding secrets that have been buried for seventy years. Written by a young woman who once worked at the greenhouse, the diary hints at a long-ago scandal involving some of Blossoms Bay's most prominent families—and a suspicious death that was never properly investigated.

As word spreads about the discovery, Gloria is suddenly surrounded by people desperate to get their hands on the diary. A wealthy developer offers to buy it at any price. A obsessive historian claims it will prove her life's work. And a mysterious stranger arrives in town with questions about the woman who wrote it. When a brutal murder rocks the greenhouse and the diary vanishes, Gloria realizes that someone will stop at nothing to keep the past buried—even if it means adding another body to the count.

With help from her loyal friends and her ever-watchful Pomeranian Azalea, Gloria must dig through decades of secrets, lies, and cover-ups to uncover a truth that powerful people have protected for three generations. Some family legacies are built on solid foundations. Others are built on something far more sinister. In the fifth installment of this charming cozy mystery series, Gloria discovers that in Blossoms Bay, the roots of the past have a way of breaking through—no matter how deep they're buried.
