On the whole, Apollo’s Outcasts is a good book, a fast read, and a story that is accessible not only to the YA audience but to an adult one as well. Allen Steele has been writing for a long time, and he knows the craft of this sort of story. It’s a strong sci-fi adventure novel with a lot of good science that doesn’t get bogged down in the detailed explanations — and, honestly, even the infodumps are interesting because, unlike fantasy novels that focus on magic, most of the stuff in Apollo’s Outcasts is not only plausible but also within our reach.
