Amazing books with intricate plots and deep characters?

My two favorites for many subplots intertwining around a central timeline are Harry Turtledove's Southern Victory series:

How Few Remain (1997)

The Great War Trilogy

American Front (1998)

Walk in Hell (1999)

Breakthroughs (2000)

The American Empire Trilogy

Blood and Iron (2001)

The Center Cannot Hold (2002)

The Victorious Opposition (2003)

The Settling Accounts Tetralogy

Return Engagement (2004)

Drive to the East (2005)

The Grapple (2006)

In at the Death (2007)

and George R R Martin's Song of Ice and Fire

A Game of Thrones 1996

A Clash of Kings 1998

A Storm of Swords 2000

A Feast for Crows 2005

A Dance with Dragons 2011

These series were both very fun to read (Martin's series isn't over yet, there are two books still being written) and conform to the type of writing you were asking about.

The Night Circus.It's a rare book that can live up to advance buzz of the sort "The Night Circus" has been getting.The prose is beautiful - not too verbose, not too simplistic. Morgenstern has the rare ability to describe her fantastical imaginings in a way that is easily accessible. Reading "The Night Circus.This book dragged painfully in the middle, piling details and uninteresting characters on top of each other until I was literally counting down the pages.

You might want to check out the His Dark Materials trilogy, the Wind on Fire trilogy, the Gemma Doyle trilogy and the Hunger Games I've heard is really good, though I haven't read it myself.

You might have read them, but if you haven't, check out 'The Girl with the Dragon Tattoo' trilogy by Steig Larsson.

THIS IS AN AMAZING BOOK! Check out 'Annabel' by Kathleen Winter.

It has everything your looking for it's perfect! Promise me you'll look it out!
