The Tor/Forge Blog has an interview with Lena Meydan. Here’s an excerpt:
Also, no one in the novel, man or vampire, knows the whole truth. In life we often do not know much, even if one person knows a little more than others. Time and history become distorted and we lose what was once the real picture. And with due diligence, any lie, after a few centuries, can become unshakable truth, especially when repeated to those who unconditionally believe you.
