Pnin (by Vladimir Nabokov)

I know; it's absurd that I hadn't read this book, Pale Fire's precursor and cousin. I can't wait to read the criticism of it, especially how it relates to Pale Fire (I noticed lots of overlap--solus rex, butterflies, reflections, and autobiographical details of Nabokov's life--and of course Pnin the character makes a cameo appearance in Pale Fire). It appears to be, at face value, a charming character study of the sympathetic titular character. But of course, there's a narrator--and to what extent he is unreliable remains to be seen. He seems to be an unsympathetic version of Nabokov himself... very intriguing.
