*contains very mild spoiler* 
 This is one of the strangest books I have ever read. It is also excellent. 
 A rough precis of the plot is that Solomon Kugel moves his family to an old house in the country, and finds he has an octogenarian Anne Frank living in his attic (yes, that Anne Frank). 
 He then engages in mental self-torture trying to decide what to do about her. To give an idea of the moral maze he gets into, he starts thinking that, as a Jew himself, he can't possibly throw her out. But then again, she's a fraud, she's supposed to have died 70 years ago, she's also ungrateful, aggressive and unhygienic, and ruining his life. 
 He then finds out that the previous owner of the house was a fifth generation German American, who also knew she was there, and he didn't throw her out, so if a *German* let her stay, he as a jew can't possibly throw her out. 
 As well as the ongoing Anne Frank problem, he is also dealing with having his mother living with the family. His mother does nothing but hark back to her terrible experiences in the Nazi concentration camps, despite not actually having been born till after the war. 
 On top of this, Kugel also has a spiritual advisor, Professor Jove, who is a force for the negative (Hitler's major problem to him was that he was an optimist, and all hope is tragic). 
 On top of this, there's also a problem with a prolific local arsonist burning down farm houses, and a paying tenant who demands access to the attic and doesn't know about the Anne Frank problem. 
 This is a very, very strange, but extremely funny book indeed, highly recommended.
