Battle Hour [Impact Series, Book Four]

Tessa Karsten has spent the last three years on the run, dodging her abusive stepfather and his dangerous paramilitary cult. She's vowed to keep her brother safe from his clutches and influence, no matter what it takes.

But now the past has caught up with her, and taken away her only family.

There's only one thing left to do, and that's to pursue her stepfather across the ruined country and save her brother from the hell that waits. Together with Alex, a college student with a terrifying past of his own, she will face the organization that once held her and her brother prisoner, and they may not survive.

The asteroid impact was only the beginning, and now it is time for war.
