This book is very well-written and I enjoyed the adventure a lot (and admittedly I do like anything that takes place on a boat) but a lot of what happened was unrealistic. Not the adventure part, but the fact that she was thirteen and traveling alone even though she was supposed to be upper class. Details, details. I was pretty young when I read this so I don't think that historical accuracy mattered to me at that point. Eleven-year-old me would give this four stars simply because it was enjoyable and there were sailors.
