Thirty Days to Love or Die

I woke up in a novel as the wife of the man who’s supposed to kill me. My plan: seduce him before he decapitates me. Simple, right? Except my cold-blooded husband is harder to fool than I thought—and his sweet, "innocent" cousin is quietly trying to poison my reputation. I fix his estates, outsmart his enemies, and somehow earn his respect. But the moment he finally looks at me like I'm the only woman alive, he gets framed for treason. What should I do now?
