The first three fairy tale retellings from the Return to the Four Kingdoms series: The Secret Princess: A Retelling of The Goose Girl, The Mystery Princess: A Retelling of Cinderella, and The Desert Princess: A Retelling of Aladdin. These interconnected fairy tale retellings each feature a different heroine who finds herself friendless in a strange land and who must fight to save her new home and win her happily ever after.

The Princess Companion: This retelling of the classic fairy tale The Princess and the Pea reimagines the risks and rewards that come when one royal family goes searching for a true princess. The Princess Fugitive: In this reimagining of the classic fairy tale Little Red Riding Hood, the girl in the red hood has been swallowed up by the wolf and must decide if she's willing to fight for her freedom. Happily Ever Afters: Sarah and Evelyn have already risked everything to help Ava win a crown. But they soon learn that a coronation is a beginning.

As the daughter of shopkeepers, Elena has always known that the mysteries of reading and writing are closed to her. Only the mageborn can risk harnessing the power unleashed from putting pen to paper. Until Elena discovers an impossible new ability and joins the elite ranks of the mages. But with the kingdom at war, the authorities can't agree if Elena is an asset, or a threat they need to eliminate. Thrust into the unknown world of the Royal Academy without friends or experience, Elena will need all of her wits, strength, and new power to carve a place for herself.

Charlotte has always longed to be accepted by her older sisters. She would gladly exchange her vaunted beauty for their friendship. But they ask a far higher price. Pushed into marriage with a stranger, Charlotte is left betrayed and alone. All she knows of her new husband is that he has secrets—and that her heart beats a little faster whenever he calls her Lottie.

Surrounded by unfamiliar politics and long-held enemies, Verene discovers that some at the Academy want her gone by whatever means necessary. As the threats grow ever more sinister, she starts to question all of her assumptions. The hardened prince might just be her best hope of survival and — even more shockingly — he might be right about her power. But as danger grows in the shadows, Verene isn't the only one in danger. If she wants to save both her old kingdom and the new one she's starting to love, she must uncover her hidden powers and take her true place among the mages.
