What made you decide that in the following book Aubrey would basically be the good guy (a bad boy, but still a good guy)?
Warning: Spoilers for In the Forests of the Night follow... (X-posted on Facebook)
When it comes to Aubrey's and Risika's complex relationship, In the Forests of the Night is only half the story. Someday, I would love to release a revised and extended version that includes Aubrey's point of view in addition to Risika's. Here are a few details it might include:
Pandora had claimed Alexander as a student; he had attacked Ather, and she had decided to retaliate by killing Alexander's sister Rachel. Why didn't she? Who do you think convinced her it would be better to change Rachel into a vampire instead of killing her?
After her change, when Risika was weak due to her refusal to feed, who convinced her that she needed to hunt?
Who finally baited her into fighting him, proving her strength and taking her rightful place as a force to be reckoned with among her own kind?
Aubrey has been around a couple thousand years. Do you think it's more likely he's stupid, or more likely that he's manipulative? Rachel never wanted to be a vampire, and maybe would have preferred death at Ather's hands back in 1704 (Did I get that date right? I don't have the text in front of me) but long-story-short: Aubrey saw her first, had his options limited by Ather's bloodclaim... and didn't want Rachel dead.
Try rereading In the Forests of the Night sometime with this point of view.
