Over nine months of war between Israel and Hamas, Palestinian families in Gaza have been uprooted repeatedly, driven back and forth across the territory to escape the fighting. Each time has meant a wrenching move to a new location and a series of crowded, temporary shelters. These displaced families don't know when they'll be allowed to return home, but they are determined not to let their house keys become keepsakes. One Palestinian man whose family has been uprooted four times said: “If my house key becomes just a memory with me moving forward, then I don’t want to live anymore.”
