I wish I could give this one another half a star. It doesn't quite make it to the "really liked it!" stage, but almost. The relationship between Hanna and Ozren seemed forced, more like an afterthought, as if it wasn't there, and her editor said, "It needs a romantic side plot, how about Hanna and Ozren?" Then, the ending's plot twist struck me as being totally unnecessary - the story of the Haggadah was fascinating enough, it didn't require the Dan Brownish finale.
All that said, I really did enjoy it. I just think it could have been better!
