I've been reading light stuff atm and just grabbed this off the "chick lit" stand at the library just before having ds2 - I struggled valiantly through to the end but was really disappointed in it. The story was turgid and predictable, the characters one-dimensional, and I felt that what could have been an interesting story with the potential for some really sinister turns, was in fact incredibly dull. The final "showdown" between the mother and son was jaw-droppingly badly written and really let the whole book down.
However I have had lots of fun picking it to pieces so maybe it was worth it
