Lone Road — a series by ShaneLucas

Annabeth and her son, Colin, are starting over in the small town of Bella Wood, where nobody knows who they are or what they've been through. Yet the ghosts of the past are right behind. Now Colin is trapped in a dying town, caught between a shadow he can't escape, and a vengeful spirit that has a dark use for him. Only Annabeth may have a way to save him. But to do that, she might be forced to accept a fate worse than death.
