Amnesia

When Alice Reed awakens from her coma, she's met with nothing. Literally. She wakes up in a house she doesn't remember is hers. Her family? Whoever they are, they're gone now. She has no memory of anything in her past after a fatal accident. Clueless, she wanders the unfamiliar city where she finds old friends whom she does not recognize. Not only friends, but the dead, who roam the streets after a virus spread through the country, killing over half of the worlds population. The virus and the dead continue to kill. Can Alice and the group of survivors survive? And will Alice ever get the chance to meet her family, or will it be too late?
