Cyllene slides her card out of her hem pocket and 'thank you's him.  (She loves her hem pocket; it's so convenient and right on her body and she doesn't have to worry about any of her things floating or drifting out of it.)

"You're welcome."

She finishes her quiche pretty enthusiastically but not so much so that she isn't occasionally distracted by interesting sights outside the window.

The sights outside the window are mostly pedestrians, nyooms, dogs, birds, and snow.

"Are you all done or still hungry?" Shavan asks when the quiche is gone.

Hungry.

He will get them a small frangipane tart to split.

It's less obviously to her tastes but she finishes it and doesn't at any point seem inclined not to.

"Do you want to do anything in particular for the rest of the day or should I just park you in the library?"

Nod nod nod nod!!  - She signs a few of the letters she remembers, not in any particular order.

"- that's a yes to the library? I don't know any sign, sorry."

Nodnod. I (she point-point-points at herself) don't know any sign.

(Or actually she mixes up some of the sound-shapes - that was a long string of words to copy - but hopefully she mostly got the point across??)

"- oh, you want to learn sign? I guess that makes sense but if I were you I'd want to learn to write instead, practically everyone can read and almost no one can sign."

Oh, nod nod.

"Do you want me to try to explain you to the librarian so she can help you, or just puzzle it out on your own?"

Cyllene holds up one finger.

"Okay." So he brings her to the library and does his best to explain her to the librarian. He gives basically the truth but doesn't signal that it's out of character, so she accepts this with reasonable grace and presents Cyllene with some of the books aimed at kids younger than her, a dictionary, and some paper and writing implements.

This doesn't warrant a maniacal laugh quite as much as discovering an avenue to do magic did, but regardless it's convenient for the other library-goers that she's categorically not in need of shushing.

She starts with a bit of handwriting practice even though that's not the most immediately useful thing she could be doing; it'll be helpful in the longer term.  After adjusting her pencil grip to one shown in the book she works at it until she can write all the letters mostly from memory and with reasonable speed, then moves on to full words and practice sentences, sometimes mixing up words in variations she thinks should probably be grammatical.

The Delayed Writing Book has some practice pangrams and poems to play with and also includes various other symbols and numerals as things to practice with, as well as ways to notate emphasis and suchlike. (The book seems to assume that she found typing easier than writing as a small child and is catching up on that now.) It says that drawing is also a good way to build up the muscles and precision involved and has some how-to-draw-this guidelines for celtic-knot type stuff and suchlike.

Humans are so clever and of course their books would be really good; she should have predicted this.  (It's not even a story or about something really important!!  They just make all of their books good apparently!)

She tries drawing two small celtic knots but it doesn't seem smart to frontload that much writing dexterity before she knows very basic vocabulary and can put it together herself, so she moves on.

The dictionary has at least one small picture on each page. It has an explanation of how the pronunciation guides work in the front matter, since spelling is not invariably an unambiguous guide there. The words are in alphabetical order - that part isn't explained, though she may notice it on her own - and each has definitions, pronunciation, and example sentences. Sometimes several words on a page share an example sentence in a pull-quote.

Oh huh.  The pronunciation guides aren't as helpful as they would be if she knew how to pronounce more than a handful of the example words, but that will probably be helpful later.  In general she thinks she's not quite at a level where the dictionary is going to be the most helpful; what's this other book like?

This one is a book of madlibs. It's made of less glossy paper and some of them are already filled in.

Some of them just confuse her but some of them have her wracked with silent giggles.  She writes down useful vocabulary as she comes across it.

Shavan comes to check on her after she's been in the library for about three hours.

By that point she's rested her head on her hand and her elbow on the table and half dozed off; she doesn't notice him approach.
