This was an intriguing and thorough overview of the state of language use in Fiji in the 1980s, with a strong focus on contact languages. Although a lot of the terms and generally accepted theories have changed since the book was published, it still offers great insight into the language situation in plantation-era Fiji. I'd read other linguistic and ethnomusicological articles about Fiji previously, but this was much more fleshed out and gave more context to the other papers I have read.
In saying that, the book does suffer from a (necessary) overreliance on very small sample sizes and pools of speakers, particularly to do with the historical contact varieties - some examples and conclusions relying on the tiniest scrap of tangential evidence. And in some ways, the scope is too broad, giving you an arbitrary collection of examples in passing and then moving right on through dozens of dialects/pidgins/other language varieties.
While I found this an interesting read, it had too broad of a scope and is now quite aged in terms of linguistic research. Really only useful if you have a specific interest in the language varieties discussed or if you have an interest in how linguistic discourse on pidgins/contact languages has developed over time.
