Q: I love books that make me laugh, and a friend told me about this book. I paid full price, and I feel somewhat had. Ms. Jensen has a gift for humor, but the plotting involved in this book is horrible. Good humor has to have some element of believability in it, and this book has none whatsoever. With a believable story line, Ms. Jensen could be among the top humor writers out there.
A:
Negative
