I am having some trouble narrowing down which one of these ww1 books I should pick.

I want to avoid books that only cover the beginning(or only the result/end ) and the lead up to the war and also books that focus too much on that combat details, for that reason I am avoiding "Guns of August", "Sleepwalkers"," The War That Ended Peace" and "The first world war by John Keegan".

Is "A World Undone" the best one to go over the whole war(Start, middle and finish) without delving into too much detail on the combat aspects? The other option I see is "Catastrophe 1914". But "A World Undone" seems the best rated on goodreads so I am leaning towards that.

I also have the same question about ww2 books. I see the following two books recommended the most often -

Inferno - Max Hastings

The second world war - Antony Beevor.

Thanks
