Lillian Kindred is an orphan girl living with her Aunt on a farm in the hills, surrounded by a very tangled forest. When she is not doing chores, she wanders the forest, looking for fairies and spirits and spirits and magical things. Aunt warns her spirits don't necessarily want rambunctious little red-haired girls bothering them, Lillian says she's not bothering anyone. She just wants to say, "Hello hello."
One day, Lillian is out wandering, and lays down under a tree to rest. She falls asleep, and is awakened by a snake biting her. It's poisonous, very poisonous, and Lillian realizes she is dying.
Many of the local cats gather around her, though, and realize that they can't save the little girl's life, but they can use cat magic to change her into something that isn't dying--a kitten. Lillian agrees, and when she wakes again, she's a kitten, and very healthy. This is when Lillian starts to get her first tough lesson in not thinking things through. She heads off for home, knowing Aunt will be worried about her.
