It's hard to judge this book. I'm not Jewish. I'm not accustomed to flow and customary options within the services. The work comes from a small organization. I expect I will be inspired by it and find several prayers or ideas for prayers when I become more accustomed to the text.
So just two observations now.
First, interleaf photos of historic Classic Reform synagogues gives the prayer book a historic feeling, and can't afford to be seen as a relic. Coming from parallel movement within liberal Protestantism, I know it is a reputation to be overcome.
Second, I wish it were more attractive. Book design is a tricky art, and would be costly. But there is something too plain about this service book. It was dropshipped to me from GIA, a hymnal publisher. I've never found GIAs work to be terribly pretty. (They published the hymnal of NACCC, which I wrote about sometime back.) But following the publication last year of New American Haggadah, (NPR) a notable work of liturgy, scholarship and art, so pedestrian a publication of a long-lasting prayer book seems like quite a waste.
And a cautionary tale for Unitarian Universalists.
