More similar tastes Rainbow - I was going to recommend Vortex and Red Phoenix
Other fiction I'd recommend includes ;
No Man's Land : Barry England. Set in Australia in the aftermath of an unspecified apocalyptic event.
The Forever War : Joe Haldeman. Epic novel of a future war spanning centuries. One of my favourite pieces of sci fi ever.
Protect and Defend : Eric L Harry. Another great read from the same author as Arc Light.
The Hunters : James Salter. A novel about early jet pilots in Korea.
