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.
Acclaimed novelist Sayed Kashua, the creator of the groundbreaking Israeli sitcom, “Arab Labor,” has been widely praised for his literary eye and deadpan wit. His new novel is considered internationally to be his most accomplished and entertaining work yet.
