I found this to be an easy and enjoyable read. The plot develops suspense and interest well, and it is easy to have sympathy with the main characters, though the ending is rather over-complicated.
A slight moan - as someone with counselling training I was quite horrified by what the therapist (a minor character) says. This would have moved the story along just as well if it had been said by a non-professional character. The police also behave rather unprofessionally but hey! It's a story! If you want something with in-depth character development and realistic procedures then this isn't the book for you, but if you are looking for a fairly light adventure/thriller/mystery then give it a try. As a UK customer it cost me £1.97 and it is well worth a couple of quid.
On the technical side, several times when Heath appears, the font size goes really small, which has the rather amusing (but difficult to read)effect of the author seeming to whisper because he's in the secret service :) I don't know if that's a problem with the original or the download.
