Depends what you're after.
I'm quite big on alternative fiction right now.
There's a great series of 9 books (with at least one more on the way) by Harry Turtledove which begins with 'How Few Remain'. The synopsis is the Confederate States of America win the US Civil War and are recognised by Britain and France, turning the US hostile to the two European countries. When the CSA purchase the provinces of Sonora and Chihuahua from cash-strapped Mexico to gain a Pacific coastline, the USA declare war on the CSA who are aided by Britain (and Canada) and France. During the course of the novel, the US in need of an ally becomes friendly with Germany
The story then moves on to the first world war in 'American Front', 'A Walk Through Hell' and 'Breakthroughs'.
The shooting of Archduke Franz Ferdinand brings Europe to war as in reality. With the US declaring support for their German Allies, the CSA supports Britain, France and Russia and fighting takes place not only in Europe, but across the USA, CSA and Canada.
The post world war 1 situation is told in 'Blood and Iron', The Centre Cannot Hold and the Victorious Opposition.'
The CSA, Britain and France have lost. Germany has taken land from France, the USA land from the CSA. Although Britain has been deprived of Canada and forced to recognise Irish independence they remain a threat. US Occupying forces face terror attacks in Canada. Inflation rocks the CSA and the Fascist Freedom Party is established, gaining popularity on those that betrayed them such as a socialist rebellion by blacks.
Return Engagements, The Drive To The East and the forthcoming book tell the tale of an alternate World War 2.
