How would Americans respond if dozens of ISIS terrorists emerged from tunnels inside a major US city like San Diego? According to a new thriller from Dan Gordon, that horrific scenario is all too possible.
Day of the Dead is his new novel based on front lines, real life experiences from last summer's war with Hamas.
They dug tunnels inside Israel and planned to kill, maim, and kidnap as many Israelis as they could.
Thankfully, the IDF stopped those deadly plans. But is the United States ready for ISIS to use already dug drug smuggling tunnels? We talked to Gordon about his book and why he feels it's a wakeup call to the United States.
