Undying Hearts (Undying Love)

Lily McLaughlin’s only focus is the safety of her daughter. She’s built a secure refuge inside her home, shielding them both from the hordes of flesh-eating zombies that roam the area, and has stayed hidden for months. But the arrival of two handsome scavengers turns her world upside down.
Flynn Irving is an Ivy League, college professor hell-bent on avenging the death of his only child. Marine, Grant Duff, has lost his only living relative in the apocalypse and suffers from debilitating PTSD. It isn’t until they meet Lily that they’re reminded what it really means to be alive.
Within in the security of a hidden survivors’ camp, Lily's attraction to both Flynn and Grant explodes in a fiery passion. As things between the threesome heat up, Lily finds herself falling for these two opposites.
Can the men work past their differences to love her? Or will their need to protect Lily drive her away from them and into something much more dangerous?
