First of a trilogy.
This is a modern and more sophisticated version of the classic "planetary adventure" style of science fiction, told from the point of view of the aliens, except that they aren't the aliens at all, they're the native species - well, one of three native sapient species - on the planet Cersi. Humans, and other species of the "trade pact union", have recently arrived on Cersi and are making things complicated.
The Tikitik, biological engineers, live in swamps which they control. The Oud, technicians of another sort, live in tunnels under the ground. And between them, on the surface, live the humanoid Om'ray, forbidden to develop technology - but gifted with Talents and "Power," which are more or less generic psionics. Some Talents are well known and controlled by the Adepts. Others pop up occasionally and must be controlled, because they might lead to change, and the arrangement between the three species, which gives the Om'ray their fragile hold on existence between the others, doesn't allow _anything_ to change. Ever. It has always been thus.
But then, during the annual wind harvest which feeds the Yena clan of Om'ray, a strange object appears in the sky and explodes, killing many of the harvesters. One consequence will be starvation, but, in the short run, the other two races want to know what's happening.
Enter our heroine,Aryl Sarc of the Yena Om'ray. In the great disaster of the harvest, she saved a dear friend, but failed to save her own brother. Worse; she saved her friend by using a new Talent that, first, endangered them both and, second, was all too likely to make the Tikitik curious if they learned of it.
Aryl is, by our standards, a preadolescent, but through the book she takes on larger and larger responsibilities until ... but, no. No spoilers here.
Czerneda writes in a fluent, practical, post-Campbellian style remniscent of writers like Mike Resnick and Jack McDevitt. Nothing in the writing is going to make you sit up and say, wow, _that_ sentence was incredible; but neither will you be distracted from the story by clunkers. I'm definitely continuing with this trilogy.
