Even after defeating her murderer, Prince Ren, Mingshin has no time to rest. The youngest prince's shocking death leaves the royal family shaken, and Mingshin is determined to get answers. She soon discovers that Wen was killed by a magical olfactory-delivered poison that drove him to suicide.

But which dark sorcerer is responsible? The Night Dragon, Ren's shadowy master, has yet to show his face. Mingshin knows it is only a matter of time before he discovers that she carries the immensely powerful Divine Stone. She already used the stone once to change the world's timeline and cannot imagine what will happen if he uses it to gain power.

As the Night Dragon closes in, Mingshin must decide whether she trusts her friends enough to share the secrets of the powerful stone she is fated to protect. Will Jieh, who has been raised to loathe the use of magic, continue loving her after he learns she's becoming a mage? Mingshin must find the courage to unveil her true powers to her friends to stop the Night Dragon from destroying this timeline once and for all.
