Life, After — Sarah Littman

Everything changes for Dani and her family when a truck loaded with explosives detonates outside the AMIA building in Buenos Aires, Argentina, killing her beloved aunt and unborn cousin. Because of the ensuing political upheaval, economic hardship, and emotional toll, Dani's family moves to the U.S. It is a terrifying place--new school, new language, new hardships--and Dani's angry father is turning into a stranger, more so everyday. Just when Dani thinks she is about to lose it, she befriends Jessica, one of the girls who has been cruelly teasing her since she arrived.
It is the most unlikely of friendships. Jessica is wealthy, groomed, spoiled. But Jessica has a past that only Dani can understand. She lost her father in 9/11. It is a friendship that allows them both to heal in unexpected and surprising ways, and changes them and their families forever.
