I love Maria V Snyder (Scent of Magic is the next book I'll be reading). Kristin Cashore and Tamora Pierce!! Other I love just as much are:
"The Witches of Eileanan" by Kate Forsyth
6 books in the series 'Dragonclaw' is the first. From Library Journal
In a land where witchcraft has been forbidden, young Isabeau learns the old ways in order to take her place in the battle to overcome the forces that threaten her world. Australian poet Forsyth's fantasy debut details a richly imagined universe with a distinctly Celtic flavor and introduces a resourceful and courageous protagonist. This first novel in a projected trilogy belongs in libraries where the demand for epic fantasy is high.
In the Celtic land of Eileanan, witches and magic have been outlawed, and those caught for practicing witchcraft are put to death! It is a land ruled by an evil Queen, where sea-dwelling Fairgean stir, and children vanish in the night. But in a valley deep in the mountains, young Isabeau grows to womanhood under the guidance of an elderly witch, and must set out on a quest, carrying the last hopes of the persecuted witches.
The "Pellinor Series" by ALISON CROGGON. It goes The Gift, The Riddle, The Crow and The Singing.
Maerad is a slave in a desperate and unforgiving settlement, taken there as a child when her family is destroyed in war. She doesn’t yet know she has inherited a powerful gift, one that marks her as a member of the noble School of Pellinor and enables her to see the world as no other can. It is only when she is discovered by Cadvan, one of the great Bards of Lirigon, that her true identity and extraordinary destiny unfold. Now, she and her mysterious teacher must embark on a treacherous, uncertain journey through a time and place where the forces of darkness wield an otherworldly terror.
"The Old Kingdom Trilogy" by Garth Nix. It goes Sabriel, Lirael and then Abhorsen.
Darker than most fantasy this is a trilogy to really immerse oneself in. Sabriel is at boarding school until her father goes missing and she is forced to return to the land of her birth and assume the role of Abhorsen, guardian of the nine levels of death and warrior against the evil forces that lurk there. With free-magic an untameable peril that daily confronts the stability of the Old Kingdom Sabriel has her work cut out to develop the necessary skills to survive the onrushing cataclysm. Imagine Harry Potter cast into the wilderness and made to fight Voldemort without the safety and education of Hogwarts and his friends. This is stripped down magical fantasy, spectacularly characterised and awesomely exciting.
For something a little different - THE LOST CONTINENT SERIES BY CATHERINE ASARO
~ The Charmed Sphere, The Misted Cliffs, The Dawn Star, The Fire Opal and The Night Bard so far.
Originally a novella entitled "Moonglow" in 2003's Charmed Destinies anthology, The Charmed Sphere is the much-expanded story about a reluctant mage and an equally reluctant heir. Chime is living an idyllic life with her family in the rural hamlet of Jacob's Vale. But her life is turned upside down when one of the King of Aronsdale's most trusted advisers, searching the kingdom for shape-mages, identifies her as a promising mage with powerful undeveloped ability. Chime reluctantly agrees to travel to Castle Suncroft, where she is to be trained in the art of magecraft -- and also groomed for her marriage to Prince Muller, the heir to the throne of Aronsdale! Muller is the nephew to the king, and the last thing he wants to do is get married and rule a kingdom. He's more concerned with fashion than affairs of state. When the King of Aronsdale dies and Muller continues to postpone his royal ascension, the leader of a neighboring kingdom -- along with an insane mage bent on destroying Aronsdale -- sees the transition as the perfect time to strike.
Other authors that are just as good but that I'll just name are:
