need book suggestions

[Glaucus]

I seem to split my reading between war books, currently reading A Million Bullets: The Real Story of the British Army in Afghanistan.

And fictions series
Lee child - Jack Reacher series
Jack Higgins - Sean Dillion series
Matthew Reilly - Shane Schofield series & Jack West Junior series
Andy Remic - Spiral series

And ok series
James Rollins - Sigma force series
Vince Flynn - Mitch Rapp series

Now finding war books is easy, but it is so hard trying to find a new series which trace the same hero in a reasonably easy to read style.

Anyone got any suggestion, or other than browsing waterstones(it never works) how I would find suitable series.
But I browse for war books and find hundreds which sound really good.
