Alice is trying to work out a series of puzzles her father had left her, which promise to show how he met her mother, who died when Alice was a baby.
Alice's father is away in Africa, leaving her with her great-Aunt Hellen alone on the big farm.
Alice and her father built treehouses and zip lines together and collected goats, alpacas, and chickens, which Alice takes care of daily.
Jamie lives next door with his grandfather and helps Alice figure out the puzzles, as they search the farm for places her father hid the next puzzle piece.
But as each puzzle shows more of the picture of Alice's mother, Alice becomes more troubled by the revelations.
