“Salt Houses,” by Hala Alyan. Places and people from the past reverberate through each character in “Salt Houses,” poet Hala Alyan’s debut novel about a Palestinian family scattered by the Israel-Palestine conflict in the 20th century. The book opens with tendrils to homes lost: Salma, reading her daughter’s future in the coffee dregs, sees turmoil, and the teacups themselves bring visions of another house in another city.
