United As One (Penguin Books)

The Mogadorian invasion has come to Earth and they have all but won the battle for our planet. Their warships loom over our most populous cities - New York City, Tokyo, Moscow, Beijing and New Delhi - and no army will risk making a move against them. The Garde have always known there is power in numbers. If they can find new allies and join forces with them, they might be able to win this war.
