Background
Abby Grant is the main characters in the series. She is the leader of the survivors. She's a woman who – having lost her husband David to the virus – is determined to find her missing son Peter, who she insists throughout the series has survived the pandemic because she did, and thinks he's inherited some immunity.
Series One
She is very concerned about Peter's well-being, as he was recovering from leukaemia and was enjoying an outdoor adventure holiday at Castle Crag Adventure Centre in the Peak District when the virus took hold. Abby has been told by Callum Brown, the last surviving instructor – and sole survivor – at Castle Crag, that Peter was one of the first boys to be taken ill and had been taken to hospital by another instructor named Phil Emerson. However, Abby failed to find Peter at the hospital and her son's present whereabouts currently remains unknown. Abby unites the series' first group, within which she strives to maintain peace and welcome new characters – as well as looking for any lead, no matter how small, that will one day reunite her with Peter. She is the only character to have survived the virus without immunity.
