I was slightly disspointed upon reading A Wind in the Door. I adore and loved A Wrinkle in Time when I read it, and I was expecting something as wonderful and beautiful as that.
Although this book is good, and is thoughtful, it lacked more of the relationships that I loved in the first book in the Time Series. I love Calvin and Meg together, and though there were some cute thoughts and things, not very many. There was also hardly any Charles Wallace, which left me a sense of a missing piece after I finished the book.
Another thing that I found annoying was how long the paragraphs were, and how sometimes I just felt like skimming the whole page for anything that seemed interesting, because the rest of it was just reiteration of things previously stated. It felt sometimes like I was hearing over and over again what I'd already heard, and not in a way that was working.
But all in all, it was still good, and worth the read, because you must read this one to read the next one, so its still good, if that makes any sense at all:)
