The Safe House on Mercer Street. Graypoint Safe Houses, #1

Some people need protection. Others need a place to disappear. Vivienne Moretti has spent years running secret safe houses throughout Graypoint-quiet apartments hidden above businesses, behind false leases, and inside buildings no one thinks to watch. Her job is simple: keep people alive long enough to start over. Then a wounded stranger arrives at her door. Luca Greer is an accountant who uncovered financial records powerful people were never supposed to see.
Now men are hunting him across the city, and the evidence he carries may expose a conspiracy reaching from Graypoint's harbor to the highest levels of power. Vivienne has protected witnesses before. She has never met one like Luca. Quietly observant and impossible to intimidate, Luca notices everything-the carefully arranged rooms, the lights left on for frightened guests, the exhaustion Vivienne hides from everyone around her.
As danger closes in, the distance between protector and witness becomes harder to maintain. Because the longer Luca stays inside the safe house on Mercer Street, the more it begins to feel like home. And home is the most dangerous thing either of them can afford. When enemies move closer and hidden networks begin to unravel, Vivienne and Luca must decide who they can trust before Graypoint's secrets consume them both.
Welcome to Graypoint. Sometimes the safest place to hide is where you finally learn to belong.
