Part two of Harrison`s trilogy is, if anything, even worse than part one in it`s portrayal of stupid Britishers versus clever Americans. I am not giving anything away by telling that the British don`t succeed with anything as the book plods to it`s foregone conclusion, even a 19th century version of Sean Connery as 007 gets killed. It is pathetic!. OK, it is supposed to be an alternate reality. Well it is certainly alternate, reality it is not. 1)I can find no evidence of an historical USS Avenger. It is an invention of the author.If Harrison is going to make up warships to suit himself, he may as well give his Americans Polaris submarines and be done with it. 2)American ironclad monitors of 1864 were so underpowerd and unseaworthy they wold have been virtually incapable of crossing the Atlantic. When one did in the late 1860`s it arrived in Le Havre with a crew so seasick they could hardly stand, much less fight a battle. Technicalities like this are simply ignored. 3)The American invasion fleet swans across the Atlantic un-challeged and un-noticed by the biggest navy in the world This is beyond belief. 4)On land the British Army are presented as cardboard cyphers to be shot down at will by American marksmen and Gatling guns Never mind that Gatlings weren`t adopted by the US Army until 1866 or that the British possessed the Whitworth breech-loader field gun,which would have made mincemeat of the Americans, Gatling guns and all. This is a poor book. If you want to read it, borrow it from the library as I did, do not waste your money on buying it.
