The Demon Lord's Amber. Marked by Darkness

She went on an excursion with a blogger friend and ended up, by chance, in another world. And now Lera stands in a nighttime clearing, and all around are dead creatures. Terrifying—so much that her heart went into her heels! And then it turns out the body isn’t hers—and there’s also a wedding just around the corner. Lord Rockwell Flanngal, who arrived with a demand for the right of first night, will no longer leave the girl alone. Lera will have to figure out what Amber is and why this demon needs it. And she also has to work at a magic academy, get a handheld stone (a familiar crystal), make new friends, and rein in her husband. And most importantly—try not to fall in love with the demon lord.
