How much do our miseries and mistakes define who we are, and just how much choice should we have regarding things that will hurt us? Those seem to be the questions at the center of this gorgeously-written, thoughtful book.
Porter is much more concerned with issues of identity than they are with the alien invasion, or what the Seep actually look like; such things are really quite irrelevant, when it comes down to it. The Seep are just a vehicle for transformation, and a catalyst for change. You could sub in any number of things to achieve the same effect -- which isn't to say the Seep aren't effective! Just that the Seep's role in the story is secondary to how Trina reacts to them.
It really did get me thinking -- would I choose grief, and the old divisions that define who I am, and longing for the past, in exchange for health, happiness, belonging? On the surface it seems like an easy question, but as Trina's journey shows, it really isn't. Those choices, those pains, make us who we are, and I don't know if I could leave it all behind either.
Thought-provoking, quiet, and beautiful.
