It really is too bad that M. I. Ross can't join an Antarctic expedition, for she certainly is keyed to the spirit of it, from every angle, and conveys more sense of reality than many actual explorers. This new book comes closer to the sheer delight of South of Zero than anything she has done since. Grand adventure, good characterization, particularly in the build-up of the feud between Jerry and Reub, a rarely subtle humor. All in all, good reading, and an ideal bridging book for those problem boys who can't be weaned from series books.
