What a great addition to Matthew Carson's Traveler novel The Backwards Mask, and a deeper exploration of a great character, Cassandra Mayfield. Carson is, as ever, in strong command of a suspenseful, military sci-fi page turner.
This enhances Mr. Carsons version of the highly recommended "Backward Mask"(BM) quite nicely showing us the voyage of the courier that played "Paul Revere". I gave it four out of five since I feel there is a bit too much "deus ex machina" in a conflict solution and the characters don't develop as good as in BM. This may be partially due to the fact that the characters from BM had a lot more pages to come alive. So say 4.5 from 5.
