This isn't my favorite book in the Time Quintent, but it's close. I love that the focus changes from Meg and/or Charles Wallace to Sandy and Dennys-- the "ordinary" ones of the family, as they say. They have their own adventure as well, which is handled with the complexity that it deserves. Looking back, there's a lot of issue packed in the book, given it's size. Sandy and Dennys can't deny that they've traveled through time and space, but they don't just accept everything either. It's refreshing to see them struggle with belief, knowledge of what happens in the future, and their own feelings. I always thought the biblical setting was extremely well-done.
