Query: I Had To Give Up On This Book And Made It Part Of All My Yesterdays!

I usually like Parker's books,and particularly when he deviates from his Spenser books. So, I really was expecting to enjoy All Our Yesterdays, probably Parker's most significant departure from his 'norm" However, much to my disappointment, I found this book to be have erratic pacing, slow to develop, and not very believable or interesting characters. As such, I wound up skimming through large passages and then, ultimately, giving up on it. There are just too many books and not enough time to waste time reading All Our Yesterdays.
