EHO's become a staple of Doug's latter work and I really enjoyed the recruitment here. Things got a bit higgledy-piggledy when we started going all uber fast mental time and optical computers hosting people rather than AIs. The Genesis of these ideas has been present in other works and it's quite strong here.

The final reveal is masterfully done, if a touch obvious to a long-time Doug fan, and this is another fabulous entry in his chronicles.
