Winnie Foster and the Tuck spring
Ten-year-old Winnie Foster finds Jesse Tuck drinking from a hidden spring in her family's wood in Treegap and learns that the Tucks stopped aging 87 years earlier after drinking from it. When a man in a yellow suit plots to sell the water, Mae Tuck kills him to protect the secret. Winnie helps Mae escape the gallows, and Jesse gives her a bottle of the water to drink at seventeen so she can marry him. In the epilogue the Tucks come back to find her gravestone: she lived a full life, married, and died in 1948, having poured the water on a toad instead.
