Another compliment read to consider is "Primal Body-Primal Mind" by Nora Gedgoudas.
Mark's PB is very well laid out and organized while Nora's PB-PM is somewhat scattered and disorganized. However, Nora goes in to far more detail (perhaps the reason for the disorganization?) on the subject and really fills in the subtopics that Mark generalized.
If people read Mark's book and follow up with Nora's, I think it can take folks to a slightly higher level.
I read McGuff and Little too and liked their approach as well.
