Fierce Secrets by Amelia Payne

Some secrets are meant to stay buried. Some loves are worth unleashing them for.

When Meredith Cassaro catches her fiancé cheating, her world shatters. Drawn into the dangerous realm of rival crime families, she finds herself unable to resist Leonardo Donati—her brother’s best friend and the city’s most feared businessman.
Leo has loved Meredith for years, but protecting her meant keeping his distance. As old secrets resurface, he must choose between keeping her in the dark or risking it all to keep her safe.

Bullets fly. Betrayals mount. And a fierce, all-consuming love might be the only thing that survives.
