Northwest Passage, Volume 2 — Scott Chantler

Rupert's Land, 1755.
After Fort Newcastle is captured by Montglave and his vicious mercenaries, Charles Lord and his rag-tag band of survivors must flee into the vast Canadian wilderness. Challenged by the hostility of the rugged north and by their pursuing enemy, their only hope is to unite the frontiersmen and people of Rupert's Land against the French in this two-fisted historical adventure. When they finally get back to Fort Newcastle, will they find victory...
...Or betrayal?
