Vicky Nguyen is the NBC News chief consumer investigative correspondent. In her new memoir, "Boat Baby", she shares her family's harrowing story of fleeing Vietnam in 1980, five years after the fall of Saigon.  Along the way, Nguyen's family relied on smugglers, encountered pirates, and eventually lived in a refugee camp on a beach in Malaysia, all while she was less than a year old.  Her family ultimately immigrated to the U.S., and she says her parents embraced the opportunity to give her a "great American childhood".  Nguyen opened up to Hoda about her decision to share her story. Through all the ups and downs of assimilation,  Nguyen says her book is "a love letter to America" - and to her parents.
