Zavcka Klist has reinvented herself: no longer the ruthless gemtech enforcer determined to keep the gems they created enslaved, she's now all about transparency and sharing the fruits of Bel'Natur's research to help gems and norms alike. Neither Aryel Morningstar nor Dr Eli Walker are convinced that Klist or Bel'Natur can have changed so dramatically, but the gems have problems that only a gemtech can solve. In exchange for their help, digital savant Herran agrees to work on Klist's latest project: reviving the science that drove mankind to the brink of extinction. Then confiscated genestock disappears from a secure government facility, and the more DI Varsi investigates, the closer she comes to the dark heart of Bel'Natur and what Zavcka Klist is really after - not to mention the secrets of Aryel Morningstar's own past . . .
