I was a whole lot more engaged by the peripheral story. Without the alien culture that has precognitive abilities, we just have a historical preservation story wrapped around a relationship story with sfnal window dressing.
I was also hoping for a bit more depth on the historical preservation story, as there are good education opportunities available to be conveyed in an entertaining fashion. I would have loved a little discussion on context, which is critical for historic preservation. If you go digging in your back yard in the suburbs and turn up an arrowhead or cannonball, it's historical but not significant. The area's been disturbed enough that the likelihood of the thing has been moved is very high, eliminating its context. Where this comes into play in my daily life is if federal funds are used to build a sidewalk, we have to send out an archaeologist to do shovel tests every 50 to 100 feet along that disturbed urbanized shoulder to document there is no context. There's enough real work they can be doing, and we're wasting time and resources looking at something that
I also run into far too many True Believers who live in a black and white world and want to save everything. People who want to save every neighborhood of 60's ranch houses for their historical significance make my head hurt.
