Star Wars is filled with wise life teachings. "Do. Or do not." "Learn to let go of everything you fear to lose." "That's not how the Force works." All important, sure, but now it can teach us something truly essential: the alphabet.

Star Wars: ABC-3PO, a clever new book by Calliope Glass and Caitlin Kennedy with illustrations by Katie Cook, takes readers young and old on an A-to-Z exploration of the characters, creatures, and Unkar Plutts of a galaxy far, far away. With each letter, a poem tells a story about its subject (think "B for Boba Fett," etc.), accompanied by bright, fun, and often in-joke laden art by Cook. StarWars.com recently spoke to the fan-favorite artist about the making of Star Wars: ABC-3PO -- which arrives June 14 -- including where the idea originated, deciding which character gets the K entry, and sneaking in a certain holographic board game. (We also snagged some exclusive preview pages and early sketches. Eat your hearts out, Bothan spies.)

StarWars.com: To start off, I just wanted to say it’s a really fun concept, and from what I understand, its origins come from the Star Wars ABC poster that you did?

Katie Cook: Yeah. Mike [Siglain, creative director of publishing at Lucasfilm], who is working on it, really liked the ABC poster that I did for Star Wars Celebration and he had an idea. He really wanted to make a kids book that was more memorable than just, you know, the stock art photos, things like that. And he brought up all of these great kids books, kind of from the '80s, with these really charming illustrations that really stick with you; the books you want to give to your kid because you really remember loving them as a kid yourself. So he asked me about a Star Wars ABC book that was not only fun illustrations, and not just "A is for Ackbar," but pairing it with a poem or something. And I think that’s kind of what we’ve done. We’ve created something that’s pretty fun and charming, and I think that all ages, and even non-kids, are gonna think that the illustrations are really fun and funky.

StarWars.com: You know, I was reading it today and I noticed there are a ton of in-jokes -- things like Leia smirking with the chain behind Jabba -- that I think parents will pick up on as they're reading it to their kids. I’m wondering if you had that stuff in mind going in?

Katie Cook: For me, Star Wars has been such a big part of my life ever since I was a kid. I think that everybody that works on Star Wars was that kid that was obsessed with Star Wars. But I almost think, at this point, like with the Jabba illustration, it's so ingrained in your mind that it’s like, “Oh, if you’re gonna put Leia in there, it’s gotta look like she’s up to something.” You can’t just have her standing there. That’s weird. But yeah, I don’t think there’s a day of my life where myself or my husband or, you know, my oldest daughter doesn’t quote Star Wars. [Laughs] So yeah, it’s just there. It’s just always there.

StarWars.com: Is there a favorite [in-joke] that you were able to sneak in?

Katie Cook: Let’s see. I think whenever C-3PO’s on the page and he always looks really concerned. Chewbacca looking angry. Of course, the Dejarik game in the Millennium Falcon on the "W is for Wookiee" page. One of my favorite things to sneak into anything is the Dejarik board. [Laughs]

StarWars.com: Why is that?

Katie Cook: I just really love it. As a kid, it was like that one little thing that I always obsessed about, these little glowing characters. Then in the new movie when all of a sudden they were back, it was like the first thing I freaked out about. Like, “Ah, the Dejarik board came on!” And of course, I draw them as these lumpy little monsters, which I really enjoy.

StarWars.com: To my very untrained eye, the art looks a little different in some places than your other Star Wars work. Maybe characters seem taller and things like that, or subtle changes to your style. Did you change anything to give it more of the storybook kind of quality you were talking about?

Katie Cook: Yeah. Usually, when I draw Darth Vader’s helmet, it’s really super simplified and cute and expressive, and with something that’s going to be a big-name licensed product and it’s going to have a lot of prints of it, I really wanted it be more recognizable as Darth’s helmet. So that way I don’t have five-year-olds pointing out that I did it wrong, like my five-year-old does. Just like, “That’s not how Darth Vader’s helmet looks.” I'm like, “I’m getting paid to draw it and you’re not, stop.” [Laughs]

So I really wanted to make everything just a touch more accurate than my more whimsical side of Star Wars. I think it adds to the storybook feel of it. And, you know, the colors I use are a really fun palette, but it’s not primaries. It’s not a Sesame Street palette. I think that it’s a really vibrant, fun book.

StarWars.com: Can you talk a bit about the process of working with the writers?

Katie Cooke: Yeah! Basically, we were going back and forth on what the poems should be about so we could work the illustrations that we really wanted into the book. And the first go around was, "All right, so, what should all of the letters be?" [Laughs] It’s almost like, you get into a room full of Star Wars nerds at that point, and you’re like, “Well, K should be for Kit Fisto." "Well, no, because with the new movie, K should be for Kylo Ren!”

StarWars.com: I was thinking Kitster.

Katie Cook: [Laughs] Mmhmm. But then you’re sitting here, and you're like, “There’s only one [Star Wars] Rebels character in here, oh my god!" Then, of course, we have to put someone else from Rebels in with Zeb, because then we’re shunning all of the Rebels characters. So that process was kind of fun, and then, you know, okay, if we’re going to do Jabba then I definitely want to have Leia in it, because that’s his ultimate downfall, and then [we move onto] getting the poems to work with everything.
