1. The Magicians trilogy by Lev Grossman
    The "Harry Potter for adults" description the first book often gets isn't accurate, but it's not too far off, either. This series is an homage to great works of fantasy, with nods to HP and a score of other titles, most notably the Narnia series.
  2. The Earthsea Cycle by Ursula K. LeGuin
    Earthsea is a vast world made up of vast seas and island nations. The people live in literate, non-industrial societies, and magic plays a major role in daily life for most of the planet's inhabitants.

  4. Finishing School series by Gail Carriger
    Sophronia is a tomboy, which makes her something of a disappointment to her mother. That's how she ends up a student at Mademoiselle Geraldine's Finishing Academy for Young Ladies of Quality.

  5. The Abhorsen series by Garth Nix
    The series begins with the story of Sabriel, a girl who has lived outside the walls of the Old Kingdom her entire life. But her father goes missing, and she has to find him.

    Set in the not-too-distant future, this story focuses on Paige Mahoney, a clairvoyant who is thrown into a secret prison because her gift is considered treason. There, she meets a race of creatures who want to help develop and use her gift.
  8. Hex Hall series by Rachel Hawkins
    Sophie Mercer is a witch, a witch who can't quite control her powers and attracts too much attention with a prom night spell gone wrong. Her punishment is being sent off to reform school for Prodigium (witches, faeries, shapeshifters), and as tends to happen, things get complicated.
  9. The Worst Witch series by Jill Murphy
    This series has been a favorite of young readers for more than 40 years! And if you thought you had to wait a long time for Harry Potter's seven books, just consider it took THIRTY-NINE years for this series to get to book 7. These are a delightful introduction to the world of witchcraft, without the darkness that permeates Harry's tale.
