M - Maryland: a Middle Temperament, by Robert J. Brugger
N - Not So Different: What You Really Want to Ask About Having a Disability (Shane Burcaw)
V - Ventus (Karl Schroeder)
A bit premature for this one.
In play:
O - Omoo, by Herman Melville
P - Polaris (Jack McDevitt)
My apologies for the error above (I once again didn’t got to the final page, but instead replied to the post at the bottom of a previous page - d’oh).
No apology needed. That happens to me sometimes. If I’m lucky, a quick run to my bookshelves gets me a title with the right letter before the edit window closes. 
Onward!
