I'm saving the sequel for my summer holidays.
The footnotes are absolutely classic. I'm pretty sure they're an "homage" to Terry Pratchett's books, but I'm not complaining. They are very funny.
It seems that a third book has been commissioned, under the working title of "The Pirates! In an Adventure with Communists". Sheer genius.
