Free Hand by E.M. Lindsey

It begins on a rainy night, trapped in an ATM vestibule.

Derek Osbourne’s life is ruled by a carefully cultivated routine, and there’s no room for change. A tattoo artist at Irons and Works, Derek spends his days hunched over a chair, and his nights pouring his trauma onto a canvas. And that’s all he has time for.
So, when a storm knocks out the power and he’s trapped with the ridiculously hot Deaf florist who just moved in across the street, he’s not sure what to do with himself. Derek owes Basil for keeping his panic at bay while they waited for the doors to open, but he’s not sure there’s room for more than friendship. With Basil’s hesitance to date a hearing man, and Derek still dealing with the trauma his abusive father left behind, happily ever after seems like it’s just a dream.

But Derek finds it difficult to stay away, and the more Basil sticks around, the more Derek starts to wonder if he might be worthy of love.
