Deadly Little Voices (a Touch novel) by Laurie Stolarz

Camelia's power of psychometry are growing. She's starting to hear voices and her pottery has become her curse, rather than her gift. Camelia must figure out who these visions are about and how to save them before it's too late. She starts getting premonitions that completely take over her body, and unfortunately they're happening in public. Meanwhile, she still has feelings for Ben, who is seeing someone else, making her emotional state even more precarious. Can she handle her new powers, and retain her sanity?

I really had forgotten all about this series, and then I realized there were two more I needed to read! I really loved this one, and enjoyed the fact that Camelia is becoming a more layered character.
