I've thought about this a lot, and the name of the series doesn't really fit with the storyline. In the first book Quinlin hinted that Sophie might be a Keeper, but they never really came back tto that, other than all the facts the Black Swan hid in her brain. Which I guess is what Quinlin was referring to. Anyway, none of those things were really secrets, and don't you have to be hiding an important secret to be a Keeper? Maybe SM just had other ideas at the beginning, but.. any other thoughts on this?
