Silent Vow by Maya Alden

In the shadows, he was hired to kill her.
In her light, he found the one thing he couldn’t destroy.

Lucian Maddox is a man of few words and even darker secrets. By day, he manages a part of the family’s media empire. By night, he’s a lethal assassin with no attachments—until his next target shatters his reality.
Calista Ferraro escaped her mafia past to run a homeless shelter and live a life of quiet purpose. But when a contract is placed on her life, her world collides with the man sent to end it.
Lucian was supposed to kill her. Instead, he falls for her.
As enemies close in, Calista begins to trust the man she believes is her protector. But when she uncovers Lucian’s truth, love may not be enough to save either of them.
