Colonization: Down to Earth marks part two of part two of Harry Turtledove's epic alternate history in which WWII gets interrupted--and violently abridged--by a hostile alien invasion. With some of the same characters introduced in the four-volume Worldwar series and Colonization: Second Contact, the story arc continues through the 1960s, as the Lizards (along with their second fleet, composed not of soldiers but of colonists) continue to grapple with their not-quite-subdued conquest, Tosev 3 (a.k.a. earth). And Turtledove's alt-'60s are not--to say the least--about peace, love, and understanding.

Now the reptilian ETs must face off against three world superpowers in an uneasy truce: the United States; Molotov's SSSR; and the psychotic, nuke-wielding Nazis under Himmler. Elsewhere, the U.K. flirts with fascism, Red China (commanded by none other than Chairman Mao) wages a bloody resistance against its scaly oppressors, and the Arab world does likewise under the guidance of Ayatollah Khomeini. As ever with Turtledove, plot takes precedence over characterizations, but his suspenseful twists and turns don't disappoint. And while Down to Earth proves a bit less martial than its predecessors, the action still satisfies--if nothing else, the bang-up finale is worth the wait. --Paul Hughes -- From Amazon.com Amazon.com Review
