Canada's First Nations is a solid piece of scholarship detailed enough to satisfy advanced historians and well written in order to please a greater audience.
Make no mistake, this is a vast topic covering 15.000 years in history and pre-history that had to be shrunk to 560 pages only. Of course there are a few omissions, of course there needed to be some sort of selection of incidents and sources. Most of the author's choice regarding her focus can be understood easily and makes the book a good read.
The only grave criticism of which the author cannot be spared is that at some places Dickason does not sufficiently question her ancient written sources, but rather takes for granted what has been said about amerindian behavioural patterns in the 16th and 17th century.
While this can be attributed to the vast undertaking itsself, it nonetheless may be one wrong approach to sources leading to a perhaps distorted picture of amerindian ancient culture.
One example: "All Iroquoians practised torture and cannibalism"....
While the first can be regarded as proven, sources related to the alledged latter behaviour are definetely not to be taken at face value, as Heidi Peter-Röcher (Kannibalismus in der Prähistorischen Forschung, Studien zu einer paradigmatischen Deutung und ihren Grundlagen.) in her doctoral thesis of 1994 (University FU Berlin) quite convincingly points out.
In fact, as Peter-Röcher succeeded to show, remarks related to cannibalism have to be taken with utmost care. Peter-Röcher goes as far as questioning the existence of such a practise in history at all and relates that there is not one single case in history when such a practise has been positively witnessed, that is neurotic missionaries - themselves living under a constant threat of getting slain - made up these stories of "Gog and Magog" in order to illustrate their braveness among the barbarians, to put it short.
Despite these flaws Canada's First Nations is a solid piece of work well worth the time it takes to read it.
