As it turns out, Elizabeth Ann Scarborough's Channeling Cleopatra did pick up after a few more chapters, and turned into a nice light action-adventure-y corporate espionage-ish the-future-is-almost-now consciousness transfer thriller with a pleasant touch of practical archaeology* in it.
I ended up quite liking it and went and bought the sequel at 25% off just before the Smashwords sale officially closed.
Mild recommend if ancient Egyptian personalities pseudo-scientifically housed within modern day hosts, and various people plotting for the prestige of such acquisitions (and trying to foil corporate figures who've figured out what other things the technology could be used for) entertains you. The sequel, Cleopatra 7.2, looks like it'll go even further in-depth on those points.
* Had a shout-out to the Amelia Peabody series, too.
