Second Person Singular by Sayed Kashua
The book at Amazon and on Kindle
His 2012 novel, Second Person Singular, is about being Arab in a majority-Jewish country, and it’s also about being a man, and a husband, and a father. In the set-up, an Arab lawyer from Jerusalem–we never learn his name–finds a love letter inside a secondhand book, written in his wife’s handwriting. It’s addressed to someone named Yonatan–a Jewish name. Consumed with jealousy, the lawyer attempts to track down the letter’s original recipient, a quest which takes him across the country–ending in a poor Arab village, just like the one where he grew up.
