The Secrets of Earth House - The Elementalists, #2

When everyone you know seems to be plotting for the throne, who do you trust? Ros went looking for love, but found betrayal instead. With her father missing and her chance at love destroyed, Rosalinde has to figure out who she can trust before it's too late. The Great Match did not turn out the way Rosalinde anticipated. She thought she'd end the week with a tolerable husband, but more importantly, a good future king.
Instead, she let her heart get swept away in a future she couldn't have, and now she has to pick up the pieces of that broken dream. The worst part--as if anything could be worse than a shattered heart--is that she lost her best friend in the process. Now there's nowhere to turn and no one to help as she struggles to find a way out of the marriage she's being made to uphold in the hopes of getting her father back. But Ros will get him back, no matter what it takes.
She has the power to destroy everything and everyone in her path to return the rightful ruler to the throne. And though the hour seems dark, there is light to be found in unanticipated places, in friends both new and old, and in the long-buried secrets finding their way out of the darkness. Ros can succeed, she WILL succeed--she is the new queen, after all, and her kingdom needs her to lead them forward.
