The cover:
I don't think that I could easily explain the cover. They rode on trains for a little while, I guess, so there's the train and maybe Jonah racing to catch up? Whatever the point, it works. And the title, Caught. Well, let's just say that it makes sense in more than one way.
Time stops in the 21st century, and Jonah and Katherine are sent back in time because Albert Einstein is thinking about the wrong things and could mess up time forever. The Einsteins have a missing child, Lieserl, who is dying of scarlet fever. The biggest problem, however, is that Mileva, Einstein's wife, knows that Jonah and Katherine are there. How can they save time when it's as if everything is working against them?
I would recommend you to read this. Not only once, but twice because it's that good. I wish I could just talk abut the ending, but that would be a major spoiler. It's so so so amazing!
I love this book and hope that you will read it. I'll post again later.
P.S. Sorry this post's a bit choppy. The "o" key on this computer only works when you stab it, so I've had to rewrite a bunch of words.
