Fax Me a Bagel by Sharon Kahn
I read the fourth in this series last year for this same challenge.
Can I just say that I love Ruby? Ruby is the best minister's wife protagonist I have read in a while. She is so honest about who she is, I hope that someday I can also be that self-aware.
I really enjoyed this novel. It's a great cozy mystery, without icky details (well, unless you count Rabbi Kevin, but I digress...), and a great mystery and some insight into synagogue life (which is not all that different from church life, really...and again, I digress...).
