Mulder and Zoon, Amsterdam 1971
I actually got this book to cut up for the pictures (old book pages can make great envelopes!) But when I started reading it I got sucked into the journey of Captain Cook. I knew a bit about his travels and how he was killed in the Hawaiian Islands, but there's a whole story of adventure here, complete with maps documenting his travels.
We're reading this chapter by chapter at bedtime. Henry's really enjoying it, but then he likes ships and sea-adventures anyway.
