If you like Robin McKinley novels

If you haven't read Robin McKinley's newest book, you might want to check it out (published in 2008):
 

Chalice.
A beekeeper by trade, Mirasol's life changes completely when she is named the new Chalice, the most important advisor to the new Master, a former priest of fire. The author of the Newbery Medal winner "The Hero and the Crown" is back with a masterful new novel--a captivating tale that reveals the healing power of duty and honor, love and honey.

Otherwise, here are some of my recent favorites:

Book of a Thousand Days, by Shannon Hale.

Fifteen-year-old Dashti, sworn to obey her sixteen-year-old mistress, the Lady Saren, shares Saren's years of punishment locked in a tower, then brings her safely to the lands of her true love, where both must hide who they are as they work as kitchen maids.

Lament: The faerie queen's deception, by Maggie Stiefvater.

On the day of an important music competition, talented but painfully introverted and nervous Deirdre Monaghan is helped to perform by the compelling and enigmatic Luke Dillon and finds herself inexorably drawn into the mysteries and dangers of the faerie world.

A Curse Dark as Gold, by Elizabeth Bunce.

Upon the death of her father, seventeen-year-old Charlotte struggles to keep the family's woolen mill running in the face of an overwhelming mortgage and what the local villagers believe is a curse, but when a man capable of spinning straw into gold appears on the scene she must decide if his help is worth the price. (This is an amazing retelling of Rumplestiltskin)

Heroes of the Valley, by Jonathan Stroud.

When young Halli Sveinsson plays a trick on Ragnor of the House of Hakonsson, he sets in motion a chain of events that will forever alter his destiny, forcing him to leave home and go on a hero's quest where he encounters highway robbers, terrifying monsters, and a girl who may finally be his match. (Epic in length but worth the ending!)

Cabinet of Wonders, by Marie Rutkoski.
 

Twelve-year-old Petra, accompanied by her magical tin spider, goes to Prague hoping to retrieve the enchanted eyes the Prince of Bohemia took from her father, and is aided in her quest by a Roma boy and his sister. (An exciting mix of fantasy, historical fiction and adventure!)

If you're looking for some other prolific authors, you might also enjoy Vivian Vande Velde and Donna Jo Napoli, who don't write entirely fantasy but are excellent writers in that genre and others.
