Shadows & Silence by London Miller

Winter Banes is a grey hat hacker of unparalleled skill, but she’s tired of living behind a screen, and she’s tired of being invisible to the one man she wants to notice her the most.
Until she meets the man without a voice …
Răzvan ‘Tăcut’ Petri—former assassin and current bank robber—hasn’t met a challenge he can’t best. Even if that
challenge comes in the form of a petite hacker who’s off-limits to him.
What started as a spark grew into flames and there was no walking away from what they had.
Răzvan will do anything to protect and keep her, but he’s not the only one.
