Connor wont accept it and returns again to Kong Sai House. While there, he sees a photo of Niran in front of the Techno Games Arcade near the Phang Nga market. Figuring that Niran might have taken Amanda there, he snoops around. He finds Amanda being held in a cell with skeletons, carcasses, and other humans in various stages of having their blood drained. Amanda and Connor escape but are attacked outside by two jai tham on a motorcycle. One drives off with Amanda the other stays to kill Connor. Just as Niran and the rest of the jai tham arrive, Sang appears. Connor grabs a motorcycle and, with Sang riding behind him, they succeed in outrunning the jai tham.Both Amanda and Connor are now faced with decisions. Amanda must decide whether to allow Niran to turn her or to keep on drinking from her, which causes acute pain. Connor has to decide whether or not to join the song neng in hopes of winning the battle with the jai tham and helping Sang to kill herself so that all vampires including him will be turned back into mortals. The alternative, if Sang is not successful, is that Connor will remain a vampire until the next Songkran eclipse rolls around in 800 years and Sang can try again. Connors decision is made doubly hard because he is attracted to Sang. Amanda decides to continue resisting, and Connor decides to become song neng. This requires being bitten by Sang. ........
