If you like The Midnighters trilogy by Scott Westerfeld
Here are some other fantasy/sci-fi/paranormal
books that you might like (some have a bit of romance in them).
A Great and Terrible Beauty by Libba Bray.
After the suspicious death of her mother in 1895, sixteen-year-old Gemma returns to England, after many years in India, to attend a finishing school where she becomes aware of her magical powers and ability to see into the spirit world. If you like this one, it is part of a series - #2 is Rebel Angels and #3 is The Sweet Far Thing.
Sabriel by Garth Nix.
Sabriel, daughter of the necromancer Abhorsen, must journey into the
mysterious and magical Old Kingdom to rescue her father from the Land of the Dead. The other 2 books that follow are Lirael and Abhorsen.
Twilight by Stephanie Meyer.
When seventeen-year-old Bella leaves Phoenix to live with her father in Forks, Washington, she meets an exquisitely handsome boy at school for whom she feels an overwhelming attraction and who she comes to realize is not wholly human. Also a trilogy, #2 is New Moon, and #3 is coming out next month-Eclipse.
Stardust by Neil Gaiman.
In the sleepy English countryside of decades past, there is a town that has stood on a jut of granite for six hundred years. And immediately to the east stands a high stone wall, for which the village is named. Here in the town of Wall, Tristran Thorn has lost his heart to the hauntingly beautiful Victoria Forester. One crisp October night, as they watch, a star falls from the sky, and Victoria promises to marry Tristran if he'll retrieve that star and bring it back for her. It is this promise that sends Tristran through the only gap in the wall, across the meadow, and into the most unforgettable adventure of his life.
Keturah and Lord Death by Martine Leavitt.
When Lord Death comes to claim sixteen-year-old Keturah while she is
lost in the King's Forest, she charms him with her story and is granted a twenty-four hour reprieve in which to seek her one true love.
The Haunting of Alaizabel Cray by Chris Wooding.
As Thaniel, a wych-hunter, and Cathaline, his friend and mentor, try to rid the alleys of London's Old Quarter of the terrible creatures that infest them, their lives become entwined with that of a woman who may be either mad or possessed.
Darkangel by Meredith Ann Pierce.
The Darkangel, a vampire of astounding beauty and youth, can only summon his full power when he finds his 14th and final bride. But for Aeriel, whom he kidnaps to serve his brides, there is something about him--something beyond his obvious evil--that makes her want to save him rather than destroy him. This is also a trilogy - #2 "A Gathering of Gargoyles"; and #3 "The Pearl of the Soul of the World."
Uglies by Scott Westerfeld.
Everybody gets to be supermodel gorgeous. What could be wrong with that? Tally is about to turn sixteen, and she can't wait. Not for her license-- for turning pretty. Another trilogy--#2 Pretties, #3 Specials.
