JJohnson,
I do have the book you ask about, and it is more of a coffee table book than anything. However, there are beautiful pictures, and a brief blurb on how each course came to being. None of the course features are particularly spectacular (with a couple exceptions), but all look fair, attractive, and interesting.
From the list, I have played:
Eagle's Landing: A solid if not spectacular course set through wetlands and a coastal forest. The finish has several holes around the inlet to the intercoastal waterway.
Shelter Harbor: Fun, different, with several great strategic holes. This course will compete with the classic-era stalwarts in RI. The hole previously mentioned is a short par four downhill with bunkers, mounding, and a hugely wide fairway and TINY green. I thought of Strantz or Engh when I was on this hole.
Turner Hill: Martin has covered the highlights/issues pretty well. 18 does look like an afterthought as a 145-yd par three headed back into the following group's approaches to the awesome 17th in front of the former monastery. The course is built for carts. I really liked #9, an uphill split-fairway par 5 with a false front green.
Widow's Walk: I don't want to get into it...too narrow, not playable. I've heard the enviros really stuck it to the developer/designer when it was built, making it the way it is. It might be better just left as a bird sanctuary or something.
