This was such a good book. Very creative. I loved Diana's aunt's house! and the idea of timewalking! I think I'll go with 4.5 stars. I enjoyed the story and the writing. It was easy to read and get caught up in the lives of the characters. As much as I enjoyed it, it was long, and I think it could have been shortened. A lot. Overall, really good. I definitely want to know what happens next!
