This book covers what might be termed the natural twentieth century US Altered History scenario but which I don’t believe anyone else has tackled. What if Japan had not just raided Pearl Harbor but actually invaded and taken Hawaii?

Days Of Infamy has the usual Turtledove modus operandi familiar from his Great War, American Empire, Settling Accounts, World War and Colonisation series which all had multi-stranded narratives, each thread from a different viewpoint character. The twist this time is we get a few Japanese to follow.

The format has the usual faults, too. The cuts between viewpoints make the flow jumpy, some characters are merely irritating and others appear solely in order to push the story on. Some of them indeed are more or less the same cardboard people from those other series (Fletch Armitage for instance is only a transplanted Sam Carsten) and too often they repeat thoughts they’ve had previously.

Offstage, the Japanese still over-run Malaya and Burma - though surely that would have been a serious overstretch (which arguably was the case in reality, even without Hawaii) - but Turtledove has of course rearranged some things to suit his narrative. Here, for example, General Yamashita is on Hawaii and not at Singapore. He gets to say similar things at the US surrender of Hawaii as he did in the real 1942, though. There is too, a nice twist on the Doolittle Raid, now launched on Hawaii and not the Japanese home islands.

Most of the viewpoint characters are actually rather uninteresting but the beach surfer type is an unusual choice of voice. In the Great War series I remember Turtledove killing off at least one of his narrators. A major fault with Days Of Infamy is you never feel any of the narrators are in real jeopardy. Only incidental characters die.
