A new vision of knights, dragons, and the fair maiden caught in between . . .   Four decades of peace have done little to ease the mistrust between humans and dragons in the kingdom of Goredd. Folding themselves into human shape, dragons attend court as ambassadors, and lend their rational, mathematical minds to universities as scholars and teachers. As the treaty's anniversary draws near, however, tensions are high.   Seraphina has reason to fear both sides. An unusually gifted musician, she joins the court just as a member of the royal family is murdered. While a sinister plot to destroy the peace is uncovered, Seraphina struggles to protect the secret behind her musical gift, one so terrible that its discovery could mean her very life. Seraphina's tortuous journey to self-acceptance will make a magical, indelible impression on its readers. Review: Amazon Best Teen Book of the Month, July 2012: In Seraphina, dragons and humans maintain an uneasy peace and for a woman who is both there is nowhere to turn for acceptance--not even within herself. Seraphina has spent her young life concealing the truth of her parentage and authentic nature, a task that proves ever more difficult when she is thrust into the spotlight of the royal court. Author Rachel Hartman’s dragons take human form but shun the messiness of human emotion by remaining “in ard” (a highly rational state of mind), while their counterparts cling to a dangerous assumption of species superiority. As the anniversary of the treaty between the two sides approaches, court intrigue reaches a fever pitch and hard-won truths, betrayals, and intricacies of the heart are laid bare. Seraphina is a beautifully complex fantasy that delves into the most basic of desires—to be loved, to belong, and to find peace in self-acceptance. --Seira Wilson Guest Review by Tamora Pierce Tamora Pierce is a best-selling author of fantasy books for teenagers. Her books, known for their teenaged girl warriors and wizards, have received critical acclaim and a strong fanbase. Her newest book, Mastiff, is the third book in The Legend of Beka Cooper series. In Seraphina's world, coldly intellectual dragons can take on the shapes--and feelings--of human beings. Sometimes this results in a surprise. Seraphina's father married a beautiful musician, and discovered too late that she was a dragon. She died, leaving him with a daughter who confuses him and his new wife and children. Now the half-dragon Seraphina is the assistant to the cranky royal music master. She is in charge of Princess Glisselda's music lessons; she books performers for the 40-year celebration of the peace treaty between dragons and humans, and she rehearses the rowdy court musicians. She has to hide the scales on her arm and around her waist, and she can never let anyone find out that Orma, her music teacher, is actually a dragon. When she plays the solo for the funeral of the realm's murdered prince, Seraphina is suddenly raised into entirely new, visible levels of peril. People she always avoided are noticing her. She has to attend social functions, where she is caught up in court politics, between those who support the treaty and those who want to destroy it. She runs afoul of conspirators who want to start the war again--one of them may be her own grandfather. She even discovers that Prince Lucian, who is betrothed to Princess Glisselda, is not only very sharp-eyed but also very agreeable to be around. He appreciates her insights on intrigue at court and in the city and uses her as an unofficial investigator into the ongoing unrest. The plot thickens. A new religious order plots riots and revolution. Exiled knights return to report an unregulated dragon flying near where the old prince was murdered. The dragons are trying to send Orma for corrective surgery--they think he's gotten too human and they want to cut those parts out of his brain. Seraphina fears that if she tells the prince and the princess what she is, they'll hate her forever, but their work to preserve the treaty celebrations is bringing them closer together. And all of them are terrified that the dragons will decide that humans are not worth the trouble, and will destroy them at last. I loved this book even more the second time I read it than I did the first. The characters are interesting and engaging, and I love the new look at dragons. For all that she's half-dragon, Seraphina is a very believable human being, caught between different loyalties and just trying to keep everyone she loves alive. But don't take my word for it--read it yourself!
