In 1889, twenty-seven-year-old Belle Carson tends the gardens of world-renowned inventor Thomas Edison on his winter estate in Fort Myers, Florida. He and his family rarely visit, but when a friend of the Edisons' drops in, she convinces Belle to join an agricultural movement sweeping the South - tomato clubs for girls. But just as Belle is blossoming as a mentor and mother figure, her romantic relationship and the precious tomato crop wither on the vine. Can Belle prove to the girls that every challenge is an opportunity to grow? Secrets, surprises, and the search for truth keep Belle - and the local newspaper - battling for answers.
