Books Read in 2015: "A Wrinkle In Time" by Madeleine L'Engle
The book I read a while back, "When You Reach Me", had a character within it reading this book, which made me realize that I've never read this series. Not bad, although it ends a little abruptly. I've got the other three queued up, and I'll see if I can get around to them.
Always tricky with a series, whether you can judge the books as individual works or if you need to think of each as a chapter in a larger work.
