Looking for a book with a strong female lead character set in a fantasy land.

[Bonafide Bookworm]

Something that's at least a few hundred pages long.

[Aerulan]

Paladin of Souls by Lois McMaster Bujold. It's the second book set in that world, the first book is excellent as well and has some great female characters but Paladin has a female main and can stand alone, though reading both would be better and more enjoyable.

Wheel of the Infinite and
The Wizard Hunters by Martha Wells. Wells writes some of my favorite fantasy books partly because her characters especially the women are so interesting and complex.

[Rosa]

Ella Enchanted
Cupid: A Tale of Love and Desire
Diary of a Fairy Godmother
The Storyteller's Daughter: A Retelling of the Arabian Nights
East
Spindle's End
Princess Academy
Bella at Midnight
The Goose Girl
The Two Princesses of Bamarre
Toads and Diamonds
Fairest
Dealing with Dragons
Book of a Thousand Days
Tree Girl

[Nora]

Sabriel and its sequels
Uprooted
Almost anything by Tamora Pierce
The Fifth Season
The Bird and the Sword

[Laura]

Ilona Andrews writes strong female leads in a sort of fantasy.

[Gillian]

The Mistborn Trilogy Boxed Set by Brandon Sanderson.
Anything by Tamora Pierce if you don't mind YA.
Un Lun Dun by China Miéville is also YA.

[Pamela]

Spinning Silver by Naomi Novik Spinning Silver

[Aerulan]

Clockwork Boys and it's sequel have a really interesting fantasy world.
Swordheart is set in the same world but a tighter focus on the characters, less epic.
All by T. Kingfisher (aka Ursula Vernon)
The female characters in all her other books are great as well.

[Karen]

I found the female MC in The Bird and the Sword annoyingly weak.

I'll throw in The Girl Who Drank the Moon for several strong female characters including the lead.

[Joseph]

Hook & Jill
The Strange Case of the Alchemist's Daughter

[Sharon]

Shades of Magic trilogy by V E Schwab. First one is A Darker Shade of Magic
Eon: Dragoneye Reborn is also very good.

[Bonafide Bookworm]

These are all very good suggestions! Thank you guys!

[Mighty_felix]

I see a few suggestions of Patricia C. Wrede's books above, but I'll also add a few more of hers: The Raven Ring. And also Mairelon the Magician and its sequel, Magician's Ward.

[Caro]

Throne of Glass

Graceling

Fire

Bitterblue

Touch of Power

Shadows

Forbidden Forest

[Kay]

seven Wild Sisters by Charles De Lint

[Sycorax]

Daughter of the Forest, Juliet Marillier
Court of Fives, Kate Elliot
The Bone Doll Twin, Lyn Flewelling

[Karen]

Beauutiful fairy lore in The Cruel Prince and the female MC is extremely strong and resourceful despite not having any advantages.

[Pamela]

Castle Hangnail by Ursula Vernon Castle Hangnail

[Brittany]

I saw a couple of suggestions for Sarah J Maas‘s Throne of Glass, but A Court of Thorns and Roses was an amazing series as well by her. Amazing world-building and unique characters.
I also second the recommendation for Forbidden Forest.

[Rouan]

Robin McKinley's The Blue Sword and The Hero and the Crown both have strong heroines.
