What do you eat when the shops run out of food? Zoe loves teaching science, she loves her garden, and most of all she loves her quiet peaceful bungalow. Then at school, people start falling ill. The virus is airborne and highly infectious. It starts with flu symptoms, confusion and sleepiness, which worsen until one day they just don’t wake up.

Luckily, when the pandemic strikes, she already has a greenhouse full of vegetable seedlings, but not everyone around is as prepared. Can she avoid the people hunting for food: the ‘knockers’ who don’t always just knock? And will her strategy of stay in, hide and wait, be enough?
