 At the end of the last book, Galen and Toraf had come to the striking realization that Emma's mother was not who she had claimed to be. She was, in fact, the missing Poseidon princess Nalia. When Of Triton begins, Emma has been kidnapped by her own mother because she is under the impression that Galen was sent on land not to find Emma and bring her back to his brother Grom, but to arrest Nalia for murdering Grom all those years ago. With a little help from Rachel and Emma, Galen is able to find them with Grom and Toraf in tow. Nalia can't believe her eyes and things seem to be okay... 
 Except for the fact that Grom, despite his brother and sister's protest, has already sealed his mating with Paca. So, Nalia, Grom, Galen, and Toraf decide to go back and show that Nalia is still alive and that Grom's union with Paca needs to be unsealed. But when they get back, some of the trackers don't recognize Nalia's pulse, and Jagen - the power hungry ass - makes everyone question whether or not it really is Nalia and if the Royals are really fit to rule.
