Journey to Cedar Creek by J. P. Yelen

Three years after the giant tsunamis that devastated humanity, successful cooperative enclaves exist, but they are far from the doomed cities. In the dying urban landscapes, those who do not band together do not survive, and groups who work toward self-sufficiency are preyed upon by competing bands of rogue militia. The grieving nation knows that complete collapse is inevitable, but the distances between the cities and scattered rural havens are not just geographical... In a world where the ruthless can act without consequence, traversing the distance becomes a heroic odyssey. Join Mel and his daughter Jenny on their journey through this violent and unpredictable new world, where the smallest success may require a monumental effort, the simplest tool may be the difference between life and death, a moments inattention may cost you everything you have won, and kindness and honor are currencies no one can afford... The journey to Cedar Creek.
