My Zombie Apocalypse Rebirth

As a zombie sank its teeth into her leg, her bodyguard and lover of three years turned his back, rescuing her scheming stepsister instead. Dying in agony, she swore she'd never love him again. Suddenly, she wakes up three months before the apocalypse. Armed with future knowledge, she secures her survival by marrying a comatose billionaire, reclaiming her mother's multi-million dollar empire, and locking her heart away from her traitorous ex.
