I'd recommend the Nights Dawn Trilogy by Peter F Hamilton, its comprised of 3 books which total about 3700 pages (dont let that put you off!), there
a hell of a read I blitzed all 3 in about a month, its hardcore sci fi with lots of AMAZING technology, massive space and land battles, theres also
plenty of sex lol.

The sprawling narrative deals with a far future where humanity struggles and wages war against past souls flooding back into the land of the
living via possession (Al Capone and Fletcher Christian are among the returnees). Hamilton's future is expansive and primarily optimistic, with huge
sentient space-cities that can closely resemble a natural Eden. He extrapolates on current trends concerning the blurring of technology with biology,
and environmental devastation. But Hamilton pulls no punches on humanity's darker side. Poverty, sexual exploitation and cruelty still dog our
civilizations in Night's Dawn, and the coalition opposing the Possessed are faced with a particularly cruel moral conundrum; they cannot destroy them
without also killing their host bodies.
The books...
The Reality Dysfunction
The Neutronium Alchemist
The Naked God
The quote below is of wiki which explains the story format...

The story is divided in many threads, based around primary, secondary and tertiary characters. These delve deeply into the rich and complex
texture of the Universe providing a great sense of verisimilitude, also exploring some of Hamilton's darker themes. These story lines include
Dariat's struggles inside Valisk, and the Deadnights' voyage to their 'Saviour'.
Theres also a book of short stories based in the same universe called "A Second Chance At Eden"...this is a good introduction book to the
universe.

These books are EPIC and I recommend them to anyone!
