With the Guardians of the Galaxy movie just a few months away I've seen a few people asking about where to start reading Marvel Cosmic or the Guardians, so I've decided to compile a list of all the comics that make up the modern Marvel Cosmic universe that inspired the movie. Not all these books have the Guardians as the main characters but but will have one or two of the members in them.

So the trades or comixology order you want to read them in is:

Annihilation Classic (it reprints the origins of Nova, Quasar, Rocket and a few other characters)

Thanos (2003-3004 mini)

Annihilation, Book One

Annihilation, Book Two

Annihilation, Book Three

Nova: Annihilation Conquest

Annihilation: Conquest, Book One (Guardians origin told in Annihilation: Star-Lord)

Nova: Knowhere - Vol. 2: Knowhere (Issue)

Annihilation: Conquest, Book Two

Guardians of the Galaxy Vol. 1: Legacy

Nova: Secret Invasion - Vol. 3

Nova: Nova Corps - Vol. 4

Guardians of the Galaxy: War of Kings, Book One

X-Men: Emperor Vulcan

X-Men: Kingbreaker

Road to War of Kings

War of Kings

Guardians of the Galaxy: War of Kings, Book Two

Nova: War of Kings

Realm of Kings

Nova: Realm of Kings

Guardians of the Galaxy: Realm of Kings

Thanos Imperative
