Chronicles of Nick Book 1: Infinit by Sherrilyn Kenyon

From chapters.ca: 

At fourteen, Nick Gautier thinks he knows everything about the world around him. Streetwise, tough and savvy, his quick sarcasm is the stuff of legends... until the night when his best friends try to kill him. Saved by a mysterious warrior who has more fighting skills than Chuck Norris, Nick is sucked into the realm of the Dark- Hunters: immortal vampire slayers who risk everything to save humanity. Nick quickly learns that the human world is only a veil for a much larger and more dangerous one: a world where the captain of the football team is a werewolf and the girl he has a crush on goes out at night to stake the undead. But before he can even learn the rules of this new world, his fellow students are turning into flesh eating zombies. And he's next on the menu. As if starting high school isn't hard enough... now Nick has to hide his new friends from his mom, his chainsaw from the principal, and keep the zombies and the demon Simi from eating his brains, all without getting grounded or suspended. How in the world is he supposed to do that?

The Mortal Instruments Book Two: City of Ashes by Cassandra Clare

From chapters.ca:
Clary Fray just wishes that her life would go back to normal. But what's normal when you're a demon- slaying Shadowhunter, your mother is in a magically induced coma, and you can suddenly see Downworlders like werewolves, vampires, and faeries? If Clary left the world of the Shadowhunters behind, it would mean more time with her best friend, Simon, who's becoming more than a friend. But the Shadowhunting world isn't ready to let her go - especially her handsome, infuriating, newfound brother, Jace. And Clary's only chance to help her mother is to track down rogue Shadowhunter Valentine, who is probably insane, certainly evil - and also her father.

Clockwork Angel by Cassandra Clare

From chapters.ca:
When sixteen- year- old Tessa Gray crosses the ocean to find her brother, her destination is England, the time is the reign of Queen Victoria, and something terrifying is waiting for her in London's Downworld, where vampires, warlocks and other supernatural folk stalk the gas-lit streets. Only the Shadowhunters, warriors dedicated to ridding the world of demons, keep order amidst the chaos. Kidnapped by the mysterious Dark Sisters, members of a secret organization called The Pandemonium Club, Tessa soon learns that she herself is a Downworlder with a rare ability: the power to transform, at will, into another person. What's more, the Magister, the shadowy figure who runs the Club, will stop at nothing to claim Tessa's power for his own. Friendless and hunted, Tessa takes refuge with the Shadowhunters of the London Institute, who swear to find her brother if she will use her power to help them. She soon finds herself fascinated by - and torn between - two best friends: James, whose fragile beauty hides a deadly secret, and blue- eyed Will, whose caustic wit and volatile moods keep everyone in his life at arm's length... everyone, that is, but Tessa. As their search draws them deep into the heart of an arcane plot that threatens to destroy the Shadowhunters, Tessa realizes that she may need to choose between saving her brother and helping her new friends save the world.... and that love may be the most dangerous magic of all.

The Mortal Instruments Book One: City of Bones by Cassandra Clare

From chapters.ca:
In City of Bones, fifteen- year- old Clary Fray is introduced to the world of the Shadowhunters, a secret cadre of warriors dedicated to driving demons out of our world. And she's introduced with a vengeance, when Clary's mother disappears and Clary herself is almost killed by a grotesque monster sent by the evil and powerful Shadowhunter, Valentine. How could a mere human survive such an attack?

I'd recommend it to anyone who enjoyed Twilight. It's full of adventure and monsters (including vampires) and a bit of romance.

Vampirates: Demons of the Ocean by Justin Somper

From chapters.ca:
Well, if pirates are bad
And vampires are worse
Then I pray that as long as I be
That though I sing of Vampirates
I never one shall see.
Twins, Connor and Grace, never dreamed that there was any truth to the Vampirate shanty their father sang to them before he died, but that was before the two were shipwrecked and separated from each other. For Connor, who is taken aboard a pirate ship, there's the chance to learn to swordfight, but for Grace, aboard a mysterious ship of vampire pirates, the danger is great. The twins want more than anything to find each other, but their time is limited and they're an ocean apart.

Twilight by Stephenie Meyer

From chapters.ca:
As Shakespeare knew, love burns high when thwarted by obstacles. In Twilight, an exquisite fantasy by Stephenie Meyer, readers discover a pair of lovers who are supremely star-crossed. Bella adores beautiful Edward, and he returns her love. But Edward is having a hard time controlling the blood lust she arouses in him, because--he's a vampire. At any moment, the intensity of their passion could drive him to kill her, and he agonizes over the danger. But, Bella would rather be dead than part from Edward, so she risks her life to stay near him, and the novel burns with the erotic tension of their dangerous and necessarily chaste relationship. Meyer has achieved quite a feat by making this scenario completely human and believable. She begins with a familiar YA premise (the new kid in school), and lulls us into thinking this will be just another realistic young adult novel. Bella has come to the small town of Forks on the gloomy Olympic Peninsula to be with her father. At school, she wonders about a group of five remarkably beautiful teens, who sit together in the cafeteria but never eat. As she grows to know, and then love, Edward, she learns their secret. They are all rescued vampires, part of a family headed by saintly Carlisle, who has inspired them to renounce human prey.
