Ashes in Winter - Rangers of Walden, #1

Surviving the winter is only half the battle... A resilient sales manager, Derek Moss, never thought he'd lead the defence of a remote ranch outside the Northern Ontario city of Sudbury. But when Cecelie, a small-time politician turned warlord, and her raiders assault the people in Whitefish, it's up to Derek to protect it or watch his friends and family die. To the east, in the now distant downtown core of Sudbury, Derek's longtime friend, Daniel, must protect a small group of survivors huddling to survive in the ruined City Hall or starve to death as the heat fails and supplies run out.  And to their west, in High Falls, Daniel's brother Garrett must keep his people from becoming the raiders he defended them from. As civilization crashes down at the height of a brutal Canadian winter and leaves the survivors reeling in the ashes of their fallen nation, these few are all that stand in the path of those who dive into the chaos...
and stepping aside is not a risk any are willing to take.
