This was an okay book.
I liked the idea of winged messengers. I also like that the matchmaking program actually allowed for same-sex matches. I still don't think a computer can predict a perfect marriage, and I certainly don't think that everyone should be forced to be run through a program and abide by whatever result the computer prints out. At least there was a suggestion that people wouldn't be bound by the results.
The plot was okay, but the "twist" was obvious from almost the beginning and the book was longer than it needed to be.
