I enjoyed Empath, it was very well written and I loved reading about Jade's abilities. I thought the descriptions of Jade's powers were quite intense and I enjoyed the characterization of her friends. The parts of the book that dealt with the killer were extremely well written and there was a decent racheting up of tension throughout the book.
The only issue I had with the book revolved about the romance. I wasn't quite sold on the main pairing, mainly because there didn't seem to be enough time for them to get to know each other. It felt as though the characters were together, because that's what the author had planned, I felt that there should have been more interaction between the two.
But that aside, I really enjoyed the book and will definitely check out the second in the series.
