Attack on Titan Volume 0

Shingeki no Kyojin Volume 0 contains prototype of original manga never published before, drawn by Isayama Hajime when he was 19 years old, for "Magazine Grand Prix" in 2006.

Attack on Titan: Before the Fall

Novels set years before the beginning of the manga.
1) Anheru works at a workshop creating protective gear/weapons for the scouting legion (the story is set before the 3D maneuver gear was invented). Anheru is a first class weapons craftsman, and therefore has direct access and also is involved in the ongoings within the scouting legion. In the story, people still didn't know about the weak points of the titans; the story is about Anheru beginning to work on the ultimate weapon/gear to fight the titans. So essentially we learn about how the 3D maneuver gear came about.
2) A baby is found crying in a mass of Titan vomit, amidst the dead titan flames. The child is called "child of titan" and is essentially hated by the people inside the walls. He also seems to grow unnaturally fast. Named Kyukuro, he parts himself from his past/upbringing and gambles on the fate of humanity by enlisting in the scouting legion. 
3) Kyukuro has survived from the outside wall: in order to defeat the titans, he gets his hands on the 3D manuever gear. Although the gear is still imperfect and causes a troublesome incident for Kyukuro, he fights the titans. Whether it is because it is his fate to fight them, or it is because of his past, he fights against them.

Adaption of Ryō Suzukaze's light novel series of the same name.

The story takes place before Hajime Isayama's original manga and follows Anheru, a member of the Survey Corps who works in weapons development. Anheru is tired of seeing the corpses of his fellow Survey Corps members, and is working to design equipment that will allow humans to be able to kill Titans. Thus far, no one has been able to find out the weak point of the Titans, and so no one has managed to kill one. However, government conservatives think that fighting against Titans is unnecessary, and order the dissolution of the Survey Corps.

Attack on Titan

Centuries ago, mankind was slaughtered to near extinction by monstrous humanoid creatures called titans, forcing humans to hide in fear behind enormous concentric walls. What makes these giants truly terrifying is that their taste for human flesh is not born out of hunger but what appears to be out of pleasure. To ensure their survival, the remnants of humanity began living within defensive barriers, resulting in one hundred years without a single titan encounter. However, that fragile calm is soon shattered when a colossal titan manages to breach the supposedly impregnable outer wall, reigniting the fight for survival against the man-eating abominations.

After witnessing a horrific personal loss at the hands of the invading creatures, Eren Yeager dedicates his life to their eradication by enlisting into the Survey Corps, an elite military unit that combats the merciless humanoids outside the protection of the walls. Based on Hajime Isayama's award-winning manga, Shingeki no Kyojin follows Eren, along with his adopted sister Mikasa Ackerman and his childhood friend Armin Arlert, as they join the brutal war against the titans and race to discover a way of defeating them before the last walls are breached.
