time travel/alternate timeline fiction
In the near future, a UN naval taskforce is sent to deal with jihadist nutjobs who've taken over Indonesia and went on a killing spree
a ship with them has an experimental weapon, which screws up, drags them back to 1942, right into the middle of the US fleet heading to Midway....
now despite what ye may think I do not hate Americans *bonks Remodious afore he can open his trap!*

so as the 1940s' Americans see the UN fleet has Japanese vessels..they naturally open fire...
result is ugly mayhem which is quite disturbing far more than say, against an enemy, as friend vs friend by accident is much more ugly.
And history is re-written
it doesn't pull any punches, the author shows the rampant racism and other problems with the 1940s
meanwhile, the future folk have been in a decades long bloody war, inclduing nukes, against jihadists, so they now have a standing order to summarily execute any war criminals they find...and since the Japanese (who're the main enemy in 1st book) engage in widespread atrocities...well, muhaha!
good, gripping stuff. highly recommend 'em

Oh and in this timeline of the future, Prince Harry is a Captain of the SAS, who're with the UN Fleet and they end up kicking some serious Nazi arse, muhah!

also the future ships have one seriously kick arse wepaon they call a "mace", cruise missile, uses a controleld fusion reaction to accelerate tungsten rods ot insane velocities, sort of like, taking a "skeet" anti tank bomblet and mizing it with a shotgun, cluster bomb, and a nuke....
imagine taking a WW2 battleship, now, imagine it is instead a tin can...and you shoot the tin can with a shotgun loaded with BB shot or small buckshot from about 15 feet...tin can, is to the battleship...ouch!!
