Ursula Poznanski.
Titles I've written about:
Erebos (2012):
Part of the reason that everyone gets so pulled into the game is the hyper-realism of it, and Poznanski really, really captures that—the fantasy sections feel just as believable and real as the real life sections. And she drops hints as to the Real Story behind at all (in other words, the solution to the mystery), but I was so involved in Nick's part of it that I—like him—couldn't see the forest for the trees. Seriously, guys. She does a fantastic job integrating multiple genres while still allowing them their distinct personalities.
