Mara thinks she's traded her soul to save her sister... until the demon who answers the circle offers a contract instead of damnation. Ten years as his negotiator in a city of predatory bargains-or walk away and watch her sister's chances vanish.Lucien looks human, smells like smoke and spice, and dismantles the very contracts his kind are feared for. He's terrifyingly powerful, infuriatingly principled, and far too gentle with the woman who keeps calling him out.As hospital boards, hidden investors, and rival demons close in, Mara becomes the sharpest weapon in Lucien's arsenal-and his greatest vulnerability. Every deal they strike pulls them deeper into danger, and into a desire they only touch after careful, whispered terms and a single safeword: ink.If she walks away, people will suffer. If she stays, she risks her heart, her future... and the one demon who's finally playing fair.
