Daybreak (Dark Age Dawning #3)

The Change Is Forever.

Their mission was to save the world.
Their destiny was to fall in love.

It's been twelve years since the Change, and Penelope Sheehan is one of the few still practicing magic for the good of humanity in this dark, dangerous world. Determined to infiltrate the notorious O'Malley organization, she poses as an abducted girl—until a furious lion thwarts her mission. When the beast turns into a devastatingly handsome man, she recognizes in him the troubled boy she once knew.

Since becoming a skinwalker, Tru Daugherty has allowed his animal nature to take over. Aloof and cynical, he takes no interest in making the world a better place. He's a creature of instinct and impulse, living only to satisfy his senses—ignoring his scarred heart. He's also the best man to help her bring down the O'Malley crime ring.

Fighting alongside the last holdouts of humanity, they unleash a passion that tempts them to risk everything for love. But if they succeed, Tru and Pen hold the power to brighten the Dark Age for all time.
