One book related directly to this area is Traplines North
http://traplinesnorth.tripod.com/ There is also Paddle, Pack and Speckled
Trout, written in 1960 by Edwin W. Mills. Traplines North is sort of an adolescent targeted story based on truth. The other one is about a dedicated trout fisherman who frequented the Nakina area and the Albany and Ogoki.
If you are interested in pictographs and Anishnabe religion, a good place to start is "Indian Rock Paintings of the Great Lakes by Selwyn Dewdney
http://www.amazon.ca/Indian-Rock-Pai.../dp/0802031722 I think you can downlaod that one for free from the Champlain collection. He also wrote the Sacred Scrolls of the Southern Ojibway, or something like that....he was a close friend of Norval Morriseau, and was very helpful in bringing Native art out of the bush, along with Jackson Pollock. Selweyn's life story, "Daylight in the Swamp
http://www.billmcleodbooks.com/daylight_review.html will give you a real good taste of the history of canoe tripping up here, and the importance of it to the growth of the country. He also gives one of the best breakdowns of the different types of bugs and the nastiness that they inflict.
More recently, Grace Raijnovich has written "Reading Rock Art", with some new interpretations to the meanings in the pictographs. I haven't finished reading that one yet.
If you really want to go esoteric with the history of the Grand medicine Society, and some spooky stuff, pick up "The Orders of the Dreamed", by Jennifer Brown and Robert Brightman. It is a summary of the diary of George Nelson, who worked in the fur trade all over the North in the early 1800's.
If you want to read about the sad reality that a lot of Nishnabe people live in now, read the highly acclaimed book by Rupert Ross, "Dancing with a Ghost". However, that read is not for the weak of heart.
I'm sure others will chime in with recommendations as well. Oh ya, have a look at the Little Canoe Atlas of the North, a monumental recording of all the canoe routes on the Canadian Shield.
