Hunter's Rocks Guide?

Looking for a guidebook for Hunter's Rocks.  The only one I've seen online that looks promising is Holzman's PA Bouldering Guidebook but I'm wary of how uncomprehensive it may be because it covers the whole state.  Does anyone have this book?  Or know of any better books out there?

It is very uncomprehensive, as is his other PA book. Honestly either find a local or use MP. Both are as good if not better than the book.

Holzman's PA guide akin to book of fables.
