Trying to remember the names of 2 books. Can you help?

Question

1) I'm trying to remember the name of a book I read in 7th grade. It was about a girl who goes into a cellar, and when she comes out she is in the past, during some war. All I can really remember about it is that she meets a girl and they exchange items so that time doesn't speed up between visits, or something like that.

2) the second book is about a man who is hired by a kingdom to steal a stone. He travels with two men, I think. He steals the stone, but pretends to lose it so he can give it to his queen. Everyone thinks his mom was a queen of theives but it turns out that his mom is the queens theif, or something. I really can't remember much. Any help would be greatful
