Marvel's "Avengers: Infinity War" canonical tie-in novel "Thanos: Titan Consumed", by Barry Lyga, revealing the origins of the 'Mad Titan', will be available November 2018:
"...Space. Reality. Mind. Power. Time. Soul. Before creation itself, there were six singularities. Then the universe exploded into existence and the remnants of these systems were forged into concentrated ingots: 'Infinity Stones'.
"Only beings of immense power can hope to wield these stones, but for those who are worthy, the powers of a god await. 'Thanos' is one such being. But he wasn't always.
"Born on a doomed world and cast out by his people for his genius, physical deviancy and pragmatic but monstrous ideas, Thanos is determined to save the galaxy from the same fate as his homeworld, no matter how many billions have to die.
"Learn the origins of the most formidable foe the 'Avengers', the 'Guardians of the Galaxy', 'Doctor Strange' and 'Black Panthe'r have ever faced—a foe whom even a group of remarkable people, pulled together to fight the battles nobody else could, will fail to stop..."
