"On his 18th birthday, Yuko Katsuragi sees something no one else can—shadows crawling into people… turning them into madmen.

Orphaned and independent, Yuko’s life has been ordinary—until he witnesses a living shadow merge with a stranger, driving the man to murder. Worse, no one else notices the darkness spreading through Tokyo’s streets.
But when Yuko tries to intervene, he catches the attention of a dragon-riding warrior from a floating kingdom—one who claims Yuko is part of a prophecy tied to the shadows.

Now, hunted by creatures that lurk in the shadows and a kingdom that does not want him, Yuko must unravel the truth.

A dark urban fantasy where a hidden war between shadows and the soldiers of light blends in the busy streets of Tokyo. One wrong step could make Yuko the villain—or the last hope."
