Wasteland — Frank Tayell

Billions died during the global civil war that followed the outbreak. Anarchy took grip. Chaos ruled. The world collapsed. In Britain, the evacuation failed. Nowhere is safe from the undead.
Three months after the outbreak, Bill Wright has found safety in a ruined Abbey in southern England, but he is still alone. All he has for company are the files sent to him before the outbreak by the shadowy Washington fixer he only knows as Sholto. On those, he believes he has found the origins of the undead, and the vast conspiracy in which he discovers he played an unwitting part.
He needs answers, and knows the only place they will be found is at the facility that created the virus. With the wasteland infested with zombies, travelling there is not easy. Motorways, reinforced during the evacuation, now form a barrier of living death, forcing him west, towards a stately home he once knew as a child. There he rescues a woman, Kim, and together they rescue two children. But as they meet more survivors, he discovers that there are more dangerous things than the undead in the British wasteland.
This is the second volume of his journal. (76,000 words)
