Wakers of the Cryocrypt

The future. The human race is extinct. Earth is ruled by "eltecs", descendants of the AIs humans created before their demise.

While searching for prehistoric cave paintings, two eltec explorers discover a hidden cryogenic crypt containing 23 perfectly preserved human bodies frozen inside crystal columns.

As eltec society argues over who might have built the crypt and what to do with it, one of its occupants is restored to life. Human beings are no longer extinct, but, for reasons of their own, not every eltec wants to see them come back. The only living man on Earth is in terrible danger.
