Jung The Drift by C.J. Tudor

Three ordinary people risk everything for a chance at redemption in this audacious, utterly gripping novel of catastrophe and survival at the end of the world, from the acclaimed author of The Chalk Man Hannah awakens to carnage, all mangled metal and shattered glass. During a hasty escape from a secluded boarding school, her coach careened over a hillside road during one of the year’s heaviest snowstorms, trapping her inside with a handful of survivors, a brewing virus, and no way to call for help. If she and the remaining few want to make it out alive, with their sanity–and secrets–intact, they’ll need to work together or they’ll be buried alive with the rest of the dead.
