Rialle has spent her whole life in the Echorium, learning to be a Singer. But after her ears distinguish a cry in the storm, she is appointed to a delegation leaving the island to talk to the mainlanders. The treaty that protects the Half Creatures like the merlee (mermaids) from being slaughtered is being broken, and the Singers intend to stop it. Kherron, another Singer in training, is also determined to get off the island, but his rebellion lands him in the middle of an international conflict and pits everyone against him.
Rialle and Kherron are a good pair of main characters, as Kherron's angry rebellion contrasts nicely against Rialle's quiet acceptance of duty. And because their motives are so different, it's interesting to see how they end up going in the same direction, to the same cities, and ultimately to the same side of the final confrontation.
The plot powers ahead with a good deal of action, but the story as a whole feels paper thin. Almost no history is given besides the fact that a treaty had been signed to protect the Half Creatures: the details of this treaty, why the nations signed it, who enforces it on the mainland when the Singers aren't there.... not to mention the gaping holes in everyone's personal history. Rialle was born and raised in the Echorium, and no more than a sentence or two is devoted to this. No childhood memories for her or Kherron, no backstory on any of the important characters like the First Singer or the Second Singer, and very little place description all lead to the story feeling tenuous.
I also mistrusted how little power the Khizpriest, in the end, was able to wield. Surely with all of the factions in the priesthood some of them would have been on the current Khizpriest's side? Or at least he'd have found support from elsewhere, in men he controlled or who wanted to control him. The Khizpriest's magic was nebulous; for that matter most of the power that was used was not explained well. It was mentioned that metal would interfere with the ability to Sing, but Kherron's bracelet did not appear to have any impact on him, where the spear of the Khizpriest did.
Rialle annoyed me severely in how often she got sick. Seasickness, altitude sickness, sickness from drinking sleeping potions or being hit upside the head---she spends the entire book ill from one thing or another, and it got quite frustrating. It was rarer to find a moment when she wasn't ready to puke her guts out.
The end of the story drops off before resolving the relationship between Kherron and Rialle. I would hope she chooses Frenn, particularly after all he went through for her, but the ending leaves everything so open it's practically up to the reader which one she chooses. Overall this was a decent enough story, but without the necessary backstory or description to make it good. I rate this book Not Recommended.
