Princess Ying Yue believed in love…once upon a time.

Yet when she’s chosen to wed the crown prince, Ying’s dreams of a fairy tale marriage quickly fall apart. Her husband-to-be is cold and indifferent, confining Ying to her room for reasons he won’t explain. Worse still are the rumors that swirl around the imperial palace: whispers of seven other royal brides who, after their own weddings, mysteriously disappeared.

Left alone with only her own reflection for company, Ying begins to see things. Strange things. Movements in the corners of her mirror. Colorful lights upon its surface. And when, on the eve of her wedding, she unwittingly tears open a gateway, she is pulled into a mirror world.

This realm is full of sentient reflections, including the enigmatic Mirror Prince. Unlike his real-world counterpart, the Mirror Prince is kind and compassionate, and before long Ying falls in love—the kind of love she always dreamed of.

But there is darkness in this new world, too.

It turns out the two worlds have a long and blood-soaked history, and Ying has a part to play in the future of them both. And the brides who came before Ying? By the time they discovered what their role was, it was already too late.
