The Enemy — Charlie Higson

A DEVASTATING DISEASE HAS STRUCK everyone over the age of sixteen. Those who didn't die from it have turned into decomposing, brainless creatures that survive by feeding on anything that's still alive including children. Young survivors have barricaded themselves in supermarkets and other buildings, fighting off attacks from the grownups, who travel in packs, like hungry dogs.

The group of kids from a store named Waitrose includes fearless fighters, clever engineers, and wise leaders. They are tight-knit and determined to survive, but they are running out of food and their scavenger hunts are growing more and more dangerous. Marauding grown-ups are picking them off one by one.

Before long the Waitrose kids are offered a safe haven in Buckingham Palace. They make their way to it, crossing London on a perilous journey that will test them in harrowing ways. But their fight to stay alive is far from over -- the threat from within the palace is as real as the one outside it.

Full of unexpected twists and quick-thinking heroes, The Enemy is a fast-paced, white-knuckle tale of survival in the face of unimaginable horror.
