One day a shipwreck happened and A Stranger Came Ashore.  The stranger was very mysterious. Robbie tries to figure out who the man really is.      Finn Learson, the stranger, was very mysterious. He was the only survivor of a shipwreck. Robbie heard him playing the violin at night when he said he hates the violin and hates playing it. Robbie recalls his grandpa, Old Da Henderson, saying that the stranger is not human. The stranger is acting weird around Robbie's family.         Old Da Henderson knows everything that is going to happen. First there is going to be a shipwreck. Next there is going to be a stick sticking out of the ground, and it  will be fire. Then a stranger is going to come. Then everything happened and a stranger with ripped and wet clothes came through the door. He said he was on a shipwreck, and he was the only survivor. The ship's name was Bergen. The man's name was Finn Learson. He acts nice to the family, but he is really bad. Robbie doesn't think he is kind. Robbie has to figure more things out about Finn Learson.       Finn Learson  is taking Elspeth to another voe on the island. It will be up to Robbie to save his sister. The voe was haunted. There was a man who didn't look like a human who always came to the voe. After the shipwreck the man stopped going to the voe. That man was was Finn Learson.       I don't recommend this book to people who like mysteries because the author doesn't explain things that well. It was pretty good at the beginning, but the end was bad.  I rate this a four out of ten.
