Escape Hour - Impact Hour, #2

The impact was only the beginning... Now reunited with her younger brother, Tessa and her band of survivors are again in trouble. Trapped in the constant night from the impact, the goal is clear: escape the city and head north to where Tessa's estranged father waits. But escaping the city won't be easy. The corrupt police chief is taking over, and Tessa's group has killed his savage son. Her stepfather is closing in by the hour, and soon, he'll find them.
And then he'll reveal Tessa's worst secret. Then, he will kill. Soon, Tessa will need to share the brutal truth with her brother. But if she reveals the truth about the past she and Brett share, it could destroy everything.
