Query: Disappointing -- A Real Sleeper!

It took a two-week vacation to get a third of the way through it. I've read most of her other books and have usually finished them in two to three days. I don't believe that I'll ever finish this one. It was slow at the start, but I kept thinking that it would get better -- NOT! My biggest regret is that I purchased it, instead of checking it out of the library! I hope this is not the start of a writing slump, as I really do enjoy her work!
