The Quantum Magician by Derek Künsken

Belisarius is a quantum man, an engineered Homo quantus who fled the powerful insight of dangerously addictive quantum senses. He found a precarious balance as a con man, but when a client offers him untold wealth to move a squadron of warships across an enemy wormhole, he must embrace his birthright to even try. In fact, the job is so big that he'll need a crew built from all the new sub-branches of humanity. If he succeeds, he might trigger an interstellar war, but success might also point the way to the next step of Homo quantus evolution.

It was an interesting premise overall, with posthumanism discussions and creepy religions. Lots going on here: complex worldbuilding. creative and unusual hard sci-fi concepts and bioengineering of specialized human sub-species.
There are different post-human beings that were heavily genetically modified, like Homo Quantus, who are able to make astounding leaps of intellectual analysis by stepping away from their individuality, Homo eridanus (The Mongrels): engineered people adapted to live in the deep-sea floor and the creepiest of all, Homo pupa (The Puppets): a type of slave species who were genetically modified to experience awe under pheromonal cues of their masters.
I gotta say some of the quantum philosophical passages about faith, existence and quantum calculations were boring to me. The part about Homo pupa and their blind worshipping was super disturbing, exploring the worst part of blind faith fanaticism.??
