I Married An Incubus by Regine Abel

A match made in Hell…

When investigative reporter Malaya Velasco accidentally uncovers the corruption of one of the highest judges of the Obosian justice system, she is framed and condemned to a life sentence on the deadly prison planet Molvi. In her despair, she begs the Prime Mating Agency for an arranged marriage with one of the Wardens of the prison. Her match? A sinfully handsome Obosian Hell Lord with a sharp tongue, intriguing piercings, and icy-blue eyes cold enough to freeze hell over.
After recently regaining freedom from enslavement, the last thing Kronos needs is more off-worlder drama, let alone a so-called human soulmate—who happens to be a criminal no less! But justice must be served, and a soul as pure and mesmerizing as Malaya’s must be protected, whatever the cost to himself.

With their enemy always two steps ahead, both the life of his mate and the future of his House are on the line. Will Kronos be the protector Malaya so desperately needs while she proves her innocence, or are they both doomed to fail?
