I downloaded this as an Amazon freebie because I like time travel. I didn't really know what else the book was going to be about to be honest. I'd recommend you not to read the full blurb since it's one of those that tell so much about the story already.
American archaeologist Rivka (who happens to know a lot of dead languages by the way) learns about Ari and his time travel device and gets trapped in the Jerusalem of 2000 years ago.
At first I thought the book was a bit too strong on the religion side, and although is was more interesting since I know less about the different groups of Jewish faith but there's a scene particularly anti-Christian (and I don't like my books anti-anything). I was afraid this would be the tone for the rest of the novel, but luckily, although religion does seem to play an important role in the rest of the novel it didn't feel pushy anymore and it didn't really bother me.
Rivka's transgression into the new society is very smooth. She happens to know the language and figures out extremely easy how it's supposed to be spoken. There are a few mentions in the beginning of her finding the right wording, but after that she can hold very long and difficult conversations. The same goes for the rest of her transgression. The story that Damien tells her is utter crap and I can't believe she fell for that even in the beginning.
Besides these things I did find myself enjoying the novel, but not so much I'm already planning to read the rest of the novels. Perhaps some day.
Transgression is the first book in the City of God series, the other books are Premonition and Retribution.
