A note to readers:
You might find yourself thinking, “I didn’t know Darien Serlast had a sister!” Indeed, he only mentions her once, early in Troubled Waters when he is taking Zoe to Chialto. Of course, he says he has two sisters and that his mother is hunti, when (it turns out) he only has one sister and his mother is torz. The only way to explain the discrepancy is to assume that Zoe’s presence left him almost too flustered to think clearly. He didn’t show it, but it was obviously true.
