Piracy is alive and well - in places like the Malacca Straits, the South China Seas, the Gulf of Aden, the islands off Brazil, the San Blas islands, and the Gulf of Mexico. Since the Achille Lauro in 1985 a major cruise ship has not been taken - but who knows... Brogan works on cruise ships and once knew Riordan in another time and place - as enemies. Now they become reluctant allies to save a ship, and exact revenge for for their own personal losses.
Cruising will never be the same again once you have read this book.
