A good read though I was disappointed that the clinching of the romance took so little time. Sometimes it's a lot more fun if they take longer to get together. I also found the change in the protagonist's a bit too fast. I totally understand she's been forced to suppress her emotions for so long. In fact, I really enjoyed that she was warring with herself over it and felt so stiff when expressing, but it felt like this was all rather too quickly forgotten when she basically defects. She starts talking like the Changelings and teasing etc immediately.
That's my personal opinion. However, I did enjoy [b:Slave to Sensation|178476|Slave to Sensation (Psy-Changeling, #1)|Nalini Singh|http://d202m5krfqbpi5.cloudfront.net/books/1347798536s/178476.jpg|172416] and would still recommend it as a good read with complex ideas and fairly compelling characters.
