I just enjoyed Anne Zabo's "Just Business." (Link below.) But my favorite Jewish M/M read is ZA Maxfield's "Secret Light." I read it before, so it doesn't count for the challenge. But I'll separately post my old review from Zon.
I read Craving Flight by Tamsen Parker. Very well done story about an orthodox Jewish woman in a convenient marriage, who discovers with great joy that her new husband is able to meet her BDSM needs.
