And actually, it IS pure gold. This is a dramatic, adventuresome book about a set of 14-year old twins (one boy, one girl) who are orphaned, then shipwrecked and rescued by separate ships. All they want is to be together - but getting there is quite a journey.
It's a juvenile book - but I can see it being enjoyed by anyone over the age of about ten. It's not bloody or gory, the story clips right along, and the characters are fantastic. There are major female and male characters, so readers of both sexes should stay engaged and interested.
Additionally, if you're into audiobooks - Daniel Philpott is absolutely awesome here. The pirates are a world-culture melting pot, and Philpott carries off their multitude of accents and vocal characterizations without a misstep.
