In this sequel to Demon Princess: Reign or Shine, author Michelle Rowen returns to the life of teenager and Demon Princess, Nikki Donovan. Nikki is determined to live a “normal” life, even after saving her father, the King of the Shadowlands, from the diabolical scheming of his sister. So, Nikki returns to Erin Heights High School hoping to be able to maintain control of her demon side and not letting anyone find out that she is only half-human. Unfortunately, Rhys, the new Faery King, has just enrolled at Erin Heights and is doing everything in his power to make sure Nikki is discovered. In Demon Princess Reign Check, the reader learns more about the Shadowlands, the Underworld, and Nikki’s friend/boyfriend Michael, as well as, her best friend, Melinda’s legacy as a demon slayer. Michelle Rowen has already indicated that there will be more books in this series, so while this book begins and ends a new chapter of Nikki’s life; it also sets readers up for more to come.
