The Light In The Lake: The Survival Lake Retreat (Prepper Trilogy, #3) [EPUB ebook] 

Book three of the Prepper Trilogy finds our band of refugees from a solar storm safely moved into a several lake cabins and trying to work on their short term and long term survival. The lake is a beautiful place for a survival retreat, but is it safe with roving groups of lake residents all looking for what meager food resources remain after a EMP event has shut down society as we know it. Can society be recreated and restarted here, or will starvation and anarchy take over? Can a simple light in the lake be the solution to survival and the reconstruction of society, or is it merely a symbol of what has been and might be yet again?
