I just started reading this story, so there'll be only a general feedback, not chapter-wise.

The idea of Clark being the only alien/survivor/Kryptonian on earth was mentioned in every third story but mostly as a passing thought only. It's interesting to see a story about some similarities between Kryptonian families whose offspring shared the same fate.

So far I immensely enjoyed this story; there may be some coincidences that have led to this point but chalked up to artistic license that's fine (Clark finds another spacecraft in China, Anna and Clark are at the same place and exposed to a noticeable amount of Kryptonite, David's only interest is observing people instead of the location). I'm impatiently waiting for Lois (or Clark) to approach Anna, as this ought to be interesting.
