Action-packed, full of mysteries, most of which get satisfactorily resolved, but more importantly, a touching romance between two old friends who bring out the best in each other.

The only thing really lacking was a final showdown between the MC and her magically evil, corporate-ladder-climbing ex, but perhaps there's a sequel in store? I would read it. Anyway, good fun and lots and lots of gore, with a strong theme of bodily invasion and reproduction. Creepy and gross, so avoid if that stuff isn't your thing.
