Tree Soup: A Stanley Wells Mystery

Stanley is sleeping in the caravan at the bottom of the garden of his new house. He awakes at the sound of an odd whooooomphing noise and goes to investigate. There appear to be new trees in the garden—very odd. And now his mom and the twins are missing. Could these things be connected? And what about Jim, the old man who lives in the woods with his parrot telling tales of the sea? Could he be involved somehow? Dr. Moon is the only person who can help Stanley with this puzzle, and luckily he's on his way.
