In his groundbreaking Worldwar series, Harry Turtledove introduced the Race, a technically-advanced army of alien lizards that struck at the battlefields where Hitler clashed with Stalin and the Japanese Empire took on the United States. They prevailed, though humanity still resisted their seemingly inevitable conquest. The Colonisation sequence continued the story of the Race's war with our kind through the 1950s and 1960s. Now, finally recognising that the humans must in the end prevail, the Race prepares to withdraw. But will they - or we - survive the final epic battles?
