A short, but rather cute book. I thought it would only be Einstein's letters to and from children, but actually almost half of it was biographical information. I appreciated this, because I didn't know as much as I thought about him, but I feel there could have been a little less (the chapter on his education, for example, really just repeated a lot of things in more detail from the biography chapter). The letters made the book worth it, though, and I wish there had been room for more. They were reproduced as originally written (except a few that had to be translated from German) and very charming.
