The Last of Love by Grace Parkes

In a world overrun by the undead, survival is everything—until love changes the game.
Lena, a former fire captain turned hardened survivor, must escort Fleur, a brilliant but enigmatic scientist, on a perilous journey to deliver a potential cure.
Tension simmers between them, but so does an undeniable chemistry. As they face relentless zombies, hostile survivors, and their own guarded hearts, their bond deepens in ways neither expected.
With humanity’s future—and their own—on the line, can love endure in a world falling apart?
