An unstoppable virus. Everything we took for granted is gone. Only the strong will survive.

In the aftermath of a devastating flu pandemic, a military-led relief effort is evacuating UK survivors to a mass quarantine zone on the Isle of Wight. In the political and moral vacuum that follows, refugees trade their freedom for food and shelter.

Riley and the others living at Hurst Castle must relocate to an abandoned hotel on the clifftops of Freshwater Bay to escape the descent into anarchy. Riley must keep her promise and leave the relative safety of their new home on the island to search for Zed's daughter in the refugee camps.
