Spark

The Underground is filled with mourners, and Christopher Ashborrow is among them. Left to pick up the pieces after a mission to the Surface goes horribly wrong, he is forced to reckon with everything left unsaid. By his side are his friends Ava, Noah, Sam, and Amy, also grappling with their own grief. Lost in darkness, his trainer Cecilia sparks a fire that could light his way... or burn him alive. Spark is the sequel to Match, a dystopia that will have you reading by flashlight well past your bedtime.
