I finally finished this one last night. I was not too impressed. It was slightly humorous throughout the entire book. I smiled a couple of times until I got to the end when he was wrapping up the story and the characters when, it seemed to me, that Lamb was taking the opportunity to solicit for a well known charity.
The whole story is centered around a parochial elementary school in 1964/65 school year. I believe that our main character is in the 5th grade. So, there is a lot of elementary school humor and humor at the expense of a couple of the nuns.
If Lamb was just wanting to do a lite hearted Christmas book, it did not work for me and I think that he missed the mark. I would not recommend this one. Save your money or make a donation to 'your' favorite charity.
