Topaz Reign

Fairy tales are simply tales, told and re-told, but changed over time. It has been four months since Maggie learned the dark truth behind the tale of the Princess and the Pea and freed Princess Lindy from the cursed Emerald. Lindy is now back in the past where she belongs, queen of her tiny Scandinavian country, and Maggie is a fully reformed ex-stalker. Except . she can't stop doing internet searches on Lindy and her country.
One morning, Maggie wakes to find history turned on its head. Apparently, you can't destroy a centuries-old curse without consequence. In order to prevent the changes in history from wiping out the present, Maggie resurrects her stalking gene and learns that fairy tales don't stay dead for long. Or at all. Back in 1623, Lindy is juggling a threat to her family, a handsome new guard she's not supposed to have feelings for, and a cursed Topaz with ties to the tale of Thumbelina.
When past and present collide, Lindy and Maggie are brought together again, and another of Andersen's tales turns from twisted fiction to chilling fact.
