The Legion is wonderfully fucked up. Things are biological and mostly gross, but that's great because the world(s) come alive thanks to pretty excellent worldbuilding. It was really refreshing to read about a fully biological SF world again and I thought this was by far the strongest aspect of the book. And some of the things the author came up with (e.g. the method for printing spare parts) are ... mind-bending. What wasn't very fun were the characters. They're every bit as fucked up as the world. But i didn't enjoy them as much. Almost every single character is stuck in a cycle of abuse. And even then I didn't really manage to care about any of them, which was a letdown. The story also didn't really grab me as much as i'd hoped. It's an amnesia fueled adventure story to save the world and the characters finding things they need or lost. It was ok.
