Heugyoseogui Sinbu

For all her life, poor Lueri has been hanging by a thread, and the situation doesn't get any better when she is forced into an unwelcome marriage. But by miracle or design, a magical invitation presents her with a way of escaping her loveless life -- by joining the empire’s Jewel Box. There, among the brilliant gemstones, she finds help in the unlikeliest of places, friends from the unlikeliest of crowds, and perhaps, something she’s been desperately yearning for until now -- true love.
