A nice enough story about Polly, one of Meg and Calvin’s kids, but it doesn’t have quite the magic of A Wrinkle in Time or the other books in that series. I’m not entirely sure what makes the difference. It might be that the science is more fantasy than science. It might be that the world-building relies a bit too much on the reader having read the other books–I didn’t feel as fully immersed in the story here.
However, if I weren’t comparing it to the amazing experience of Wrinkle, this book would do quite well. It’s well written, with great characters and complex problems that come to a satisfying, not too simplistic, resolution. A good book. Not, perhaps, one I’ll keep coming back to, but one I’m glad I read.
