This is my favorite YA fantasy series of all times (including Harry Potter as MG). Celaena Sardothian is not only an outstanding assassin, she's also a reader. Maas excelled in creating a character that is everything that I want to be, but also allowed me to sympathize.
After serving out a year of hard labor in the salt mines of Endovier for her crimes, 18-year-old assassin Celaena Sardothien is dragged before the Crown Prince. Prince Dorian offers her her freedom on one condition: she must act as his champion in a competition to find a new royal assassin.
Her opponents are men-thieves and assassins and warriors from across the empire, each sponsored by a member of the king's council. If she beats her opponents in a series of eliminations, she'll serve the kingdom for three years and then be granted her freedom. Celaena finds her training sessions with the captain of the guard, Westfall, challenging and exhilirating. But she's bored stiff by court life. Things get a little more interesting when the prince starts to show interest in her... but it's the gruff Captain Westfall who seems to understand her best.
Then one of the other contestants turns up dead... quickly followed by another. Can Celaena figure out who the killer is before she becomes a victim? As the young assassin investigates, her search leads her to discover a greater destiny than she could possibly have imagined.
I LOVE this series. The romance is top-notch, the world building is amazing, and the characters are well developed. Cassandra Clare is one of the best YA authors of the decade. That's why The Mortal Instruments comes in a close second.
The year is 1878. Tessa Gray descends into London’s dark supernatural underworld in search of her missing brother. She soon discovers that her only allies are the demon-slaying Shadowhunters—including Will and Jem, the mysterious boys she is attracted to. Soon they find themselves up against the Pandemonium Club, a secret organization of vampires, demons, warlocks, and humans. Equipped with a magical army of unstoppable clockwork creatures, the Club is out to rule the British Empire, and only Tessa and her allies can stop them...
Once again, and amazing series by the master of YA fantasy.
When fifteen-year-old Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder― much less a murder committed by three teenagers covered with strange tattoos and brandishing bizarre weapons. Then the body disappears into thin air. It's hard to call the police when the murderers are invisible to everyone else and when there is nothing―not even a smear of blood―to show that a boy has died. Or was he a boy?
This is Clary's first meeting with the Shadowhunters, warriors dedicated to ridding the earth of demons. It's also her first encounter with Jace, a Shadowhunter who looks a little like an angel and acts a lot like a jerk. Within twenty-four hours Clary is pulled into Jace's world with a vengeance, when her mother disappears and Clary herself is attacked by a demon. But why would demons be interested in ordinary mundanes like Clary and her mother? And how did Clary suddenly get the Sight? The Shadowhunters would like to know...
This series was amazing! Unfortunately, though, it went downhill from the first book. If you are not looking for a look series at the moment, I would consider just reading Graceling, as it could act as a stand alone. It's main character is possibly my most favorite bad a** heroin of all time. I greatly encourage you to read this trilogy if you haven't already.
Katsa has been able to kill a man with her bare hands since she was eight - she's a Graceling, one of the rare people in her land born with an extreme skill. As niece of the king, she should be able to live a life of privilege, but Graced as she is with killing, she is forced to work as the king's thug.
When she first meets Prince Po, Graced with combat skills, Katsa has no hint of how her life is about to change.
She never expects to become Po's friend.
She never expects to learn a new truth about her own Grace - or about a terrible secret that lies hidden far away...
Okay, so technically this series is Middle Grade. But it deserves a mention in this list, as it is honestly the series that started my "obsession" with books. My best friend recommended it to me in 3rd grade, and Percy Jackson has honestly changed my life.
Percy Jackson is a good kid, but he can't seem to focus on his schoolwork or control his temper. And lately, being away at boarding school is only getting worse—Percy could have sworn his pre-algebra teacher turned into a monster and tried to kill him. When Percy's mom finds out, she knows it's time that he knew the truth about where he came from, and that he go to the one place he'll be safe. She sends Percy to Camp Half Blood, a summer camp for demigods (on Long Island), where he learns that the father he never knew is Poseidon, God of the Sea. Soon a mystery unfolds and together with his friends—one a satyr and the other the demigod daughter of Athena—Percy sets out on a quest across the United States to reach the gates of the Underworld (located in a recording studio in Hollywood) and prevent a catastrophic war between the gods.
This series is a bit of a guilty pleasure for me. I started it young and was looking for romance, not particularly wonderful righting. However, I feel as if the writing did advance as the series did. If you're looking for a fun read, part of a wonderful series that can last quite a while (especially since there's a spin-off) look no further.
Lissa Dragomir is a Moroi princess: a mortal vampire with a rare gift for harnessing the earth's magic. She must be protected at all times from Strigoi; the fiercest vampires - the ones who never die. The powerful blend of human and vampire blood that flows through Rose Hathaway, Lissa's best friend, makes her a dhampir. Rose is dedicated to a dangerous life of protecting Lissa from the Strigoi, who are hell-bent on making Lissa one of them.
After two years of freedom, Rose and Lissa are caught and dragged back to St. Vladimir's Academy, a school for vampire royalty and their guardians-to-be, hidden in the deep forests of Montana. But inside the iron gates, life is even more fraught with danger... and the Strigoi are always close by.
Rose and Lissa must navigate their dangerous world, confront the temptations of forbidden love, and never once let their guard down, lest the evil undead make Lissa one of them forever...
