Sabotaged by Margaret Peterson Haddix

I am at a far distance in this book, and it is good. In time traveling, there is something to do with a TV screen, but I don't know what it means. I will be asking a question now. Were are they going? There is something to do with the Spain. A boy named Jonah has nothing to do with any of this, but his sister does. The two don't get along, and don't talk much. There is also someone named Virginia Dare. There dog is named Dare. I will now ask some more question. Who are Chip and Alex? How did they get kidnapped? Will they ever come back? I was surprised when the author said Jonah was taken from his regular timeline, and he has nothing to do with time travel. To finish this post I will ask one more question. Who is Virginia Dare?
