Sig and Anna's father dies after falling through the ice in their small mining town. Shortly after, a huge, evil man Wolff comes looking for the gold that their father supposedly stole from him. He holds the kids hostage and threatens to kill them if they don't tell him where the gold is and they have no idea what he is talking about. Showing courage, the two end up making the odds a bit more even. A good, quick read that YA boys would especially like, I enjoyed this book. I borrowed this book from the library.
