Book 3 of The Agency
It's kind of ridiculous how much I love these books.
The research doesn't feel terribly strong-- especially, in some ways, in this one...
But the story is so fun I just don't care.
Mary is such an engaging heroine that I just don't care.
Even when I briefly thought "Okay this side story is a little old" I didn't really care enough to be bothered.
This is always listed, everywhere I've seen it described, as a trilogy. Which would make this the end.
But there are rumors about a 4th book....
And that would be seriously cool.
Until then, I'll reread the trilogy.
