There are 4 books in the series:
-The Goose Girl
"On her way to marry a prince she's never met, Princess Anidori is betrayed by her guards and her lady-in-waiting and must become a goose girl to survive until she can reveal her true identity and reclaim the crown that is rightfully hers."
-Enna Burning
"Enna and Princess Isi became fast friends in The Goose Girl, but after Isi married Prince Geric, Enna returned to the forest. Enna's simple life changes forever when she learns to wield fire and burn anything at will. Enna is convinced that she can use her ability for good-to fight Tira, the kingdom threatening the Bayern borders-and goes on secret raids to set fire to the Tiran camps and villages. But as the power of the fire grows stronger, she is less able to control her need to burn. In her recklessness she is captured by the Tiran army and held captive by a handsome, manipulative young captain who drugs her to keep her under his influence. Can Isi and her old friends Finn and Razo rescue her without sacrificing themselves? And with the fire still consuming her, will Enna find a way to manage the gift that threatens to destroy her?"
-River Secrets
"Razo has never been anything but ordinary. He’s not very fast, or tall, or strong, so when he’s invited to join an elite mission escorting the ambassador into Tira, Bayern’s great enemy, he’s sure it’s only out of pity. But when they arrive in the strange southern country, it is Razo who finds the first dead body. As they try to learn more from the Tirans about the ever increasing murders, Razo is the only Bayern soldier able to befriend both the high and low born, including the beautiful Lady Dasha. And as Razo finds allies among the Tirans, he realizes that it may be up to him to get the Bayern army safely home again."
-Forest Born
"Rin is sure that something is wrong with her…something really bad. Something that is keeping her from feeling at home in the Forest homestead where she’s lived all her life. Something that is keeping her from trusting herself with anyone at all. When her brother Razo returns from the city for a visit, she accompanies him to the palace, hoping that she can find peace away from home. But war has come to Bayern again, and Rin is compelled to join the queen and her closest allies—magical girls Rin thinks of as the Fire Sisters—as they venture into the Forest toward Kel, the land where someone seems to want them all dead. Many beloved Bayern characters reappear in this story, but it is Rin’s own journey of discovering how to balance the good and the bad in herself that drives this compelling adventure.Once again, Newbery Honor-winning author Shannon Hale brings readers to a world where great friendships, unexpected plot twists, and a little dose of magic make for incredible storytelling."
