This was the email I received earlier today:
Hi Richard. Another one of out partners has reviewed your book for final editing. Please check the edits she made and accept them when appropriate or make corrections. This will be our final reading, so please make sure that all the edits are done carefully and do not interfere with the rest of the ext. I would suggest having one more person read it before sending it back to us, just to make sure the edits are incorporated smoothly. Thanks.
About half a dozen questions left over from the prior revision. The editor still has trouble understanding what rain smoke is. Need to think about that one.
