In the book I've read, it's called the mysterious bennadict society three kids father has gotten kidnapped and its up to these brilliant kids to save him he's given them every lesson they Need to live but the must go on a huge journey to the top of a very tall mountain to get their father but the villain is relentless to stop even if that it mean it has to kill them. They don't know where he's going next nor what his reason for kidnapping their father is.
The only problem is now that they found the villain they set up a base camp near then but when they wake up they realize that they are drugged and are tied to a piano going down the snowy mountain into the ocean but while this is happening the villain has kidnapped the youngest child because she is the one in the family with the most common sense. Being at a very young age he thinks
he can change her so she'll work for him.
But the problem is while she's being kidnapped the two older kids are formulating a plan to get both the father and their sister out of his evil grasps so the faster can explain everything and Just return to normal once the stop the villains. I think the moral of the story is that family is the most important thing you can have because in the end when everything is said and done all you have is each other. Even when things go down hill.
