Algebra der Nacht (Perfect Paperback)

The blend of fact and fiction adds depth but also raises questions about authenticity. I wonder what inspired these choices and how much research went into it.

The detailed descriptions of the era are fascinating, but at times I wanted more suspense. Was that balance intentional to build atmosphere?

The secret society aspect felt so intriguing and mysterious. I'm curious whether the author based it on real lore or created it from scratch.
