Light of Dawn (Remnant)

Light of Dawn (Remnant) by Chapman, Vannetta. library edition. ISBN: 9781683245094.

For nine months, since a devastating solar flare caused a complete failure of the electrical grid, Shelby Sparks and her diabetic son, Carter, have been living at the ranch of Shelby’s high school sweetheart, Max Berkman. Mostly insulated from the chaos surrounding them, Shelby and Max discover that the Texas government has fled the capitol and is barely maintaining control of the state. The governor needs volunteers to search for the new federal government, but no one knows exactly where it might be located — if it even still exists — or what perils await those brave enough to take on the mission.
