I was surprised at how much I enjoyed this novel.
I appreciated (Read: Loved) the fact that Pen and Blake worked from the beginning and their relationship was earned. They never had that 'miscommunication leads to a falling out in the second act only to be brought back together in the third' crap that has been over used since the second item used it. When there was a problem, they talked it out, and they both respected each other's boundaries. This is how we need to represent relationships.
This book wins all the things. We need more books like this. Please give it a read of you haven't.
