From the publisher:

At Marvel in the 1970s, no one mastered the startling scope of cosmic adventure like Jim Starlin! In this star-spanning spectacle, Starlin evolved Adam Warlock to the next level, imbuing the character with the inner demons of a man-god on the brink of insanity. Forced to confront an evil version of himself and the nihilistic menace Thanos, Warlock's conflicts weren't just knuckle-grinding throw-downs -- they were existential struggles for his very soul. Featuring the first-ever assembling of the Infinity Gems, the debuts of Gamora and Pip the Troll, and an all-out struggle to save the universe -- joined by the Avengers, Captain Marvel and Spider-Man! And now, the full epic grandeur of Starlin's saga is unleashed on the oversized pages of a Gallery Edition!
