This was a fairly good book with a whole fictional universe created. I liked Meg's (The main character's) feelings and thoughts which are described perfectly. It is a book for 2nd to 6th graders but I won't limit the grades below who will also enjoy it if they are willing to read it. The reason I didn't rate it 5 stars was because even if the author (Madeleine L'Engle) was very imaginative, the description of her fictional universe was vague. The characters and setting is also reeling towards fantasy a bit more than Sci-Fi which is not my liking. But overall, for the young readers who like fantasy, it is a good book.
