I didn't run into any more issues, and sending them manually worked.
Looking at the code, I can see what is happening, and, in one way, I'm not that surprised. But, it usually works and I can't think of a reason that sending multiple books would trigger an error when sending a single book doesn't. I'll have to think about it. Or hope Joel notices and pops in.
