And what characters. Going from the opening premise that this is an "alternate" Earth (from ours, anyways) where a US Destroyer (the USS Walker) and a Japanese Battlecruiser (The Amagi) found its way there through some freaky portal during the early stages of the War in the Pacific during World War II. This Earth, while being fairly the same geographically as the one they'd left behind, was one where evolution had taken different forks in the road eons ago.
Instead of the "dominant" species being, well, us, for instance, there are intelligent races of lemur-based evolution (Lemurians) as well as reptilian-based evolution (The Griks, possible defendants of Velociraptors).
These two "peoples" are at war with each other and, in this particular book, there is also other entries into this war. A war, mind you, that is turning into this particular Earth's own "World War," in which the American forces side with the Lemurians while the Japanese find an alliance with the Grik to be beneficial to themselves. This, by the way, is just my own small understanding of what has happened and is happening in this series, based on my reading of this one particular novel.
My apologies if I have botched it up and you are a fan of the series reading this and yelling at your screen that I'm an idiot.
Filled with the same "gung-ho" spirit of the very best WWII fiction as well as some of the best writing I've seen in quite some time that dealt with differing evolution "what ifs?" Taylor Anderson's Firestorm is just … well it's just a really really good book.
I highly recommend it. Now then, can any of you loan me the first books in the series? Anyone? Anyone? Bueller?
