A collection of three essays by a pivotal figure in both Polynesian archaeology and in seeing the meaning and implications of that for the larger story of human settlement in both the past and in the space-oriented future. All worth reading. The first essay, describing the experiences with reconstructing past Polynesian voyaging techniques to support the thesis of "intentional" voyaging, was particularly interesting. The second, describing the rather sad story of how Tahitian culture has fared under French colonial rule and the rise of Tahiti as a testing ground for nuclear weapons, was compelling as well. The third is his classic, "One Species or a Million", discussing how past experience suggests future space settlement and the implications thereof. Absolutely a must-read for space enthusiasts, but it is the same essay collected in "Interstellar Migration and the Human Experience" which has other material likely to interest those literate about space settlement, so if picking up just one, I'd suggest the larger volume.
