Ultraviolet (Ultraviolet, #1) - R.J. Anderson I loved the book right until where the whole alien thing came in to it, at that point the story just seemed to go downhill for me.
The whole synesthesia aspect of it was very interesting and I liked the other characters (Pine Hill patients) but I couldn't find myself caring for it much after a certain point...
Judging by other reviews I must be the one of the only ones that wasn't that impressed with Ultraviolet.
