There's a novel coming out today that's a bit like The Da Vinci Code (yuck), but using Jewish and ancient Roman history as the driving forces behind its adventures. The Last Ember by Daniel Levin.
Hopefully the writing will be better than Dan Brown's (it could hardly be worse). I have high hopes. I'm fairly certain that the historical data will be more accurate than Brown's evil haze of misinformation and misunderstanding.
The novel's gotten good reviews (click the link above to read them on Amazon) as well as endorsements from, among others, Elie Wiesel and Alan Dershowitz. Impressive.
