Her  psy-changelin  series, is one of the best series I’ve ever read. She created a world full of fantasy, romance, adventure and a touch of mistery, where the reader can journey with joy.
Here is how the author herself explain how she had the idea to write this series of book:

Nalini: “I’ve always been fascinated by psychic powers, by the idea that we might have unawakened abilities inside of us. Experiments have shown that humans use only a tiny percentage of their brains. But what if we were suddenly able to access that unused remainder–isn’t it possible that abilities now considered paranormal might then become run of the mill? As a child I simply thought it would be really awesome to be able to read other people’s minds. However, as I grew older, the ethical considerations began to loom large. Then I began thinking that maybe I didn’t want to be reading everyone’s minds. But what if real telepaths had no control over their abilities? What if they couldn’t stop? Then one day in February 2005, it was as if my various thoughts about psychic powers had spent enough time mixing. The idea that came to me was full-blown. And it was deceptively simple: What if the flip side of incredible psychic power was insanity of the worst kind, the kind that drove you to murder? What would you do to survive?That nightmare question was the beginnin of the first book of this series, Slave to sensation.”

This series, for now, is composed by three books, but two more are arriving, and more will come in the next years.

Used to cold silence, Faith NightStar is suddenly being tormented by dark visions of blood and murder. A bad sign for anyone, but worse for Faith, an F-Psy with the highly sought after ability to predict the future. Then the visions show her something even more dangerous-aching need…exquisite pleasure. But so powerful is her sight, so fragile the state of her mind, that the very emotions she yearns to embrace could be the end of her. Changeling Vaughn D’Angelo can take either man or jaguar form, but it is his animal side that is overwhelmingly drawn to Faith. The jaguar’s instinct is to claim this woman it finds so utterly fascinating and the man has no argument. But while Vaughn craves sensation and hungers to pleasure Faith in every way, desire is a danger that could snap the last threads of her sanity. And there are Psy who need Faith’s sight for their own purposes. They must keep her silenced-and keep her from Vaughn…
