Elisa from Rae Carson's GIRL OF FIRE AND THORNS trilogy definitely has this moment. Born with a magical Godstone that indicates her vitality, Elisa has always felt like a disappointment next to her sister and constantly eats her feelings. When she's taken in marriage, becomes queen, and is then kidnapped and marched across the desert, that's something that, at first, she feels ill-equipped to handle.
Cinderella: A character who transforms
In Tahereh Mafi's SHATTER ME trilogy, Juliet has to learn to love and forgive herself for the superpower she possesses, which kills those she touches. She also, over time, learns to embrace the power and use it in her fight to make her dystopian world better. It's a transformation of confidence, and it feels like classic Cinderella to me.
Maggie Stiefvater's RAVEN CYCLE is eclectic and ethereal all around, a series full of fae and prophecy with a plot I don't even know how to properly describe but definitely love. The characters definitely form an eclectic and complex group that pushes forward the strangeness of the series. I especially love Blue's family of aunts, who are all unusual and strong women with paranormal gifts.
Sleeping Beauty: A book that put you to sleep
SEEKER by Arwen Elys Dayton just didn't do it for me. Nah, bro, nah.
The Lion King: A character with a traumatic childhood
Jazz from Barry Lyga's I HUNT KILLERS trilogy was raised by a terrible father, an infamous, psychopathic serial killer who taught him all the ways of murder. Jazz spends the books using these unique skills to hunt down murderers, all the while terrified that he'll turn into one himself. His childhood, in fact, is so messed up, that I'm not even sure I recommend reading the last book of the trilogy. Super graphic. But the first book is A++.
Beauty and the Beast: A 'beast' of a book that intimidated you, but you loved
I read a lot very quickly, as y'all might have noticed, and so length doesn't tend to deter me. But the decent length of Fyodor Dostoyevsky's CRIME AND PUNISHMENT mixed with the fact that it's a #SERIOUS book with a #SERIOUS title and a #SERIOUS-ly complicated author's name did put me off at first. I guess it's literary fiction that I find intimidating. But I really love this classic, as it turns out, with all the psychology and Christian imagery it possesses. Russians are a'ight, y'all.
Aladdin: A character who gets their wish granted
Cress, from Marissa Meyer's LUNAR CHRONICLES, is a sweet, young genius who has lived her whole life isolated in a spaceship, dreaming of freedom and of the very handsome Captain Thorne. Who then shows up to rescue her, because #awesome, that's why. Does it go perfectly? No. But Cress is bae, and I want to hug her for forever, and I'm happy she got out of that stupid spaceship. <3 <3 <3
Mulan: A character who pretends to be something (s)he is not
Since the dressing-up-as-a-boy thing is already on board here, I offer you Iolanthe from Sherry Thomas's ELEMENTAL TRILOGY, a powerful elemental mage who dresses up as a boy in order to attend Eton with Titus, the prince of the magical realm. This trilogy's pretty awesome, guys, and I LOVE Iolanthe.
Toy Story: A book with characters you'd love to come to life
Seeing as Peeta is my book boyfriend, obviously I'm going to have to pick THE HUNGER GAMES, because Peeta. Peeeeeeeeeeeeetaaaaaaaaaaa. <3 Most of the other characters would be pretty legit to have in real life too, like Rue, and Prim, and Finnick, and I guess Katniss. I mean, Katniss might have to stay fictional, if I'm going to win me some Peeta. But whatever the case, we'll just keep Snow and Coin out of it, all right?
Disney's Descendants: A favorite villain or morally ambiguous character
Cam, from my top fave UNWIND DYSTOLOGY by Neal Shusterman, is probably the most fascinating character of the whole thing: a new human being created entirely from Unwind parts into a mosaic that's meant to be perfection. He's raised by a nasty corporation, an innocent caught up in a moral war that he can't even begin to understand, and is in love with a girl who hates what he is. Yay Cam!
