Proteus Books in Order

In the twenty-second century, biological techniques allow people to alter their bodies into new forms. The promise of healing and transformation brings unauthorized experiments and deeper threats, forcing humanity to question what remains human when appearance can be changed.

Failures in body-altering technology threaten communities that depend on constant physical adaptation to survive in space. Expert Behrooz Wolf is summoned to investigate, but his own mental collapse and an enemy awaiting disaster make the crisis harder to contain.

Technology can reshape humans and animals, leaving a formal Humanity Test to distinguish their origins. When violent creatures pass that test despite appearing biologically inhuman, threatened settlements face a dilemma: killing them would violate the law protecting human life.
