** spoiler alert ** Given Mr. Dekker's recurring Christian themes, I made the erroneous assumption that the the title of this work referred to The Holy Trinity. Turns out I was wrong. When all is said and done, it turns out to be a rather clever title.

With that said, I need to admit that I saw the fact that Kevin and Slater were the same person coming long before it was even mentioned by the characters. What I did not see coming was that Samantha was also part of Kevin's many personalities. Nice work, Ted.

With THAT said, in the end, I think there are some minor plot holes with this thread. For example, Kevin signing Sam's name to the guest registry at the hotel. It makes sense that Samantha has always been "Sam" to Kevin. What doesnt' make sense is that, in the given momnet, Kevin actually WAS Sam, so it seems that Sam would have signed "Samantha" since that would be "her given name." Like I said, a minor flaw, but it's a flaw just the same.

The minor flaws do not keep me from being intrigued by Dekker's other work. I found this book to be pretty engaging and hope that I am just as intrigued by The Circle series, which I will be starting soon.
