"She was a thin woman in a mustard-yellow suit, with a yellowish complexion, short-cropped, Rusty red hair, and a stiff posture. She reminded Reynie of a giant walking pencil."

-The Mysterious Benedict Society, Trenton Lee Stewart

"It has often been said that one should never judge a book by its cover. As any serious reader can tell you, this is terrible advice. Serious readers know the singular pleasure of handling a well-made book-the heft and texture of the case, the rasp of the spine as you lift the cover, the sweet, dusty aroma of yellowed pages as they pass between your fingers. A book is more than a vessel of ideas: it is a living thing in need of love, warmth, and protection."

"Sophie loved books beyond reason. Indeed, she loved them more than she loved the world around her. It was the very thing that made her unique, until it made her dangerous."

- Sophie Quire and the Last Storyguard, Jonathan Auxier

"She was found by Michael Jones, who was ten at the time, and who dutifully put her in the lost property cupboard." -The Bookshop Girl, Sylvia Bishop

"There once was a boy named Milo who didn't know what to do with himself-not just sometimes, but always." and everything that follows- The Phantom Tollbooth, Norton Juster

"Come October, I look like I'm ablaze. It's a miracle the fire department doesn't try to hose me down every Autumn."

"You might be surprised to learn that all red oaks are named Red.

Likewise, all sugar maples are called Sugar. All junipers are called Juniper. And all boojum trees are called Boojum.

That's how it is in the tree world. We don't need names to tell us apart.

Imagine a classroom where every child is named Melvin. Imagine the poor teacher trying to take attendance each morning.

It's a good thing trees don't go to school."

-The Wishtree, Katherine Applegate

"As the the vacuum cleaner roared towards him, he did not (for instance), think, Here, at last, is my fate come to meet me!

He did not think, Oh, please give me one more chance and I will be good.

What he thought was Man, I sure am hungry."

-Flora and Ulysses, Kate DiCamillo 

"I noticed several weird things about the surfboarding cat." 

-Crenshaw, Katherine Applegate

"Mrs. Rachel Lynde lived just where the Avonlea main road dipped down into a little hollow, fringed with alders and ladies' eardrops and traversed by a brooke that had its source away back in the woods of the old Cuthbert place; it was reputed to be an intricate, headlong brook in its earlier course through those woods, with dark secrets of pool and cascade; but by the time it reached Lynde's Hollow it was a quiet, well-conducted stream, for not even a brook could run past Mrs. Rachel Lynde's door without due regard for decency and decorum; it probably was conscious that Mrs. Rachel was sitting at her window, keeping a sharp eye on everything that passed, from brooks and children up, and that if she noticed anything odd or out of place she would never rest until she had fettered out the whys and wherefores thereof."

-Anne of Green Gables, Lucy Maude Montgomery

"Jonnhy's only true companion was a melancholic chicken with a peculiar name. Her name was: Pestilence and Famine."

-The Purloining of Prince Oleomargarine, Mark Twain and Philip Stead

"Marnie is my BFF and therefore must receive all of my thoughts, rambling or otherwise."

And I will post more later! 

Yes! Books in the Grishaverse do have really good quotes. King of Scars duology has some I really like too. Here is one: 

“Elizaveta nodded. ‘Most women suffer thorns for the sake of the flowers. But we who wield power adorn ourselves in flowers to hide the sting of our thorns.’

Be sweeter. Be gentler. Smile when you are suffering. Zoya had ignored these lessons, often to her detriment. She was all thorns” (387).
