In the middle of the holidays, a biological attack wreaks havoc on the U.S.

The virus is quick. Deadly. Unstoppable. The country is left in tatters.

For Isaac Race, it's especially bitter. After the death of his parents and sister, he was just getting his life back on track - the weaponized virus changes all that.

Battered by the fresh deaths of his foster parents, but hardened by the year he's endured, he emerges from the temporary safety of his home to seek out other survivors during the most vicious winter on record.

With the help of his friend Luke, he soon discovers that 250 perilous miles stand between them and the only possible haven, three states away, in the White Mountains of New Hampshire.

It won't be easy. The invaders and the freezing temperatures aren't the only dangers facing them at the end of the world. To survive, they'll have to risk everything and do anything to protect themselves in a world where trust and safety have been shattered.

If you're a fan of post-apocalyptic thrillers, whatever you do, don't miss Hell Week, book one of the epic America Falls survival series.
