Shadow bruja Ren Santiago was relentlessly pursued by the evil Aztec Lords of Night, who claimed that she was destined to be their queen, a destiny she wasn't willing to accept. So she chose death instead. Too bad death wasn't the answer to her problems. Ren soon realizes she must return to the land of the living to make things right. Unfortunately, that means negotiating with Ixtab, queen of the underworld. Ixtab offers her ten days aboveground in exchange for the discarded crown of jade and shadow. If Ren fails, she will return to the darkness for eternity. Ren agrees, knowing full well that she also has to save her friends Marco, Monty, and Edison and, while she's at it, put those pesky Lords of Night back to sleep forever. The only problem is, Ren lost her shadow magic and time rope when she lost her life. How will Ren manage to accomplish what feels impossible? The answer lies not in manipulating shadows or time, but in recognizing the awesome power that has always been inside her.
