There are as many wacky ideas for novels as there are novelists. More, actually; many novelists move closer to the outer edges of imagination (theirs; ours) with each book. As proof, I submit "The Family Chao," the third novel by Lan Samantha Chang, in which she reimagines Fyodor Dostoevsky's epic "The Brothers Karamazov" as a contemporary Chinese American family drama.
