" This was a pretty good book, not the best I've read from L'Engle but still entertaining. I enjoyed the mystery aspect of the plot, some of the characters who were introduced, and learning a great deal about Antarctica in the process, including a ton of new info on penguins. Recommended if you're already a Vicky Austin fan and enjoy light adventure, a little mystery, and some education with your fiction. "
