So good and not just because a lot of it takes place in Vermont. This is a fantasy story but only sort of. The basic conceit" what if there were doors to other worlds that you could get to but they were hard to find. What if some people wanted them closed? What if other people wanted them open? How could you move among and between them? There’s a LOT going on in this story which mostly happens through the eyes of a young, female protagonist. A nicely complex story that nonetheless both wraps up and leaves a door open for more story to come.
