With her fiance now her ex-fiance, Ace has hightailed it back to Bugtussle, Mississippi, and back to her Gramma Jones's house. Her best friends, Lilly and Chloe, are delighted she's back, but Ace still has some challenges ahead of her. For one thing, her replacement as Bugtussle High School's art teacher, Cameron Becker, refuses to vacate the position. So Ace is stuck working as a substitute teacher while harboring fantasies of running Miss Becker out of town. On top of that, Lilly and Chloe are obsessed with setting her up on less-than-romantic blind dates-even though all she wants is a break from her pitiful love life. To ease her troubled mind, Ace resolves to restore her grandmother's gardens to their former glory. But in the well-worn gardening book she's dug out of her grandmother's attic there are a series of suspicious notes that indicate her grandmother may have had a special someone in her past. Now, with her faithful chiweenie, Buster Loo, by her side, Ace is determined to get to the bottom of her grandmother's secret life, all the while hoping her own life isn't about to implode.
