The Wayward Tower: A Rapunzel Novella - The Twin Kingdoms, #3

Trapped in a tower Aria knows how to escape imprisonment. All she needs to do is to lead Prince Victor to his death. But she has no desire to become a murderer or assist the man that holds her captive. Instead, Aria discovers a possible solution in unfamiliar magic. The Wayward Paths may lead her to freedom, but they will require her to come face to face with the shadows of her past. The foolish prince Victor's life is in danger.
After barely escaping a deadly masquerade, he finds himself a target of The Mage King, an ancient being who requires royal blood. Not that Victor takes that too seriously. He'd rather think about Aria, the beautiful and mysterious woman that visits him in his dreams. Aria's past holds the key to the identity of The Mage King, but will their encounters provide him with answers or result in his demise? What dangers lie on The Wayward Paths?
