I kept getting the feeling I'd read this before, but I couldn’t quite remember it. Three main characters come together to retrieve the stone that holds the magic of the volcano in check and prevents it from rising and destroying the city. Princess Chandra, a wizard of the nine, who is trying to avoid an arranged marriage to Prince Darvish of Ischia, a dissolute younger son with an alcohol problem. Into this situation falls Aaron, former can chief's son turned runaway and thief. The fun of this book is the changing relationship between these three protagonists and their eventual resolution. (And the recovery of the stone, of course, despite pirates, storms and traitors.) A fun book. Recommended.
