The Lost King by T.M. Kohl

She’s trapped on another world. With a strange voice in her head. What will it take to get back to Earth? Lauren Strauss wanted a normal life, but fate had another idea in mind. Plagued by bizarre dreams and questions about her family’s past, Lauren hopes the day of her college graduation will lead to her getting answers... When she’s caught up in a violent attack that rocks downtown Chicago, her mother arms her with a mysterious amulet which she will soon realize has a mind of its own. Tearing her from Earth and dropping her in an alien place, it abandons Lauren and leaves her to navigate this new world by herself. She will do anything to return home. But can she?
