Set first in Roswell New Mexico in 1947, and later in America during the 1962 Cuban Missile Crisis, 1947 continues the story of the Roswell UFO incident. Toni is a fifteen year-old alien orphaned when her parents' flying saucer is shot down over Roswell New Mexico on July 8, 1947. She's been raised in hiding by former Air Force Nurse Naomi Selff who stole her as an infant from the wreckage. Believing the child she names Antonia after her mother, and mistakingly believing that Toni is the only alien on earth, Naomi teaches her to hide in plain sight by camouflaging her alien appearance and abilities. Naomi thinks she's succeeded until Toni's first kiss.
There were two flying saucers over Roswell in 1947, and one escaped. Daniel is the son of the surviving crew. His parents remained on Earth to search for Toni, and after fifteen years, they've become marooned. Believing they have no chance of rescue and that their survival depends upon masquerading as humans, Daniel's parents haven't told him he's an alien. Daniel is enjoying the life of a somewhat short and sun-sensitive, but otherwise normal high school freshman living in suburbia. He's unaware that his parents, known to their neighbors as John and Mary Smith, occasionally use their flying saucer, now in serious disrepair, to save the world from the men who murdered Toni's parents in 1947. Everything seems to be going well, until Daniel meets Toni.
