Last Descendants Launch Party!

In just a few weeks, the first of my YA Assassin’s Creed novels will be released into the wild. Last Descendants comes out on August 30th, and I’ll be having a launch party to celebrate. If you live in the Salt Lake City area, I’d love to see you. If you live elsewhere, I’ll be posting tour dates as they’re confirmed. I hope to host similar events in additional cities if I can make it work. Now, the details:

Island of the Sun cover reveal!

A few weeks ago, Mr. Schu was kind enough to reveal the cover to my next novel on his site, but now I’d like to reveal it here. With much excitement, I present to you Island of the Sun, the sequel to The Arctic Code and the second book in The Dark Gravity Sequence!

IslandoftheSun hc (1)


Here’s the official synopsis:

Eleanor has shut down the mysterious Concentrator in the arctic, but her mission is far from over. The Earth is still spinning out of its orbit, and growing colder by the day. Their only chance is to find the other Concentrators imbedded around the world and deactivate them before it’s too late.

But doing so won’t be easy. The Global Energy Trust has branded Eleanor, her mom, and her friends international terrorists, and are tracking their every move. The G.E.T. will stop at nothing to harness the power of the Concentrators in order to preserve the select few people they deem worthy, and Eleanor is soon forced to ask herself whether it’s worth risking the lives of the entire human race for a slim chance to save them.

The second book in Matthew J. Kirby‘s Dark Gravity Sequence is a breathless race across a planet perilously close to extinction, one that will find Eleanor and her friends questioning their connections to it—and to each other.

The Arctic Code Book Launch!

photo (1)I have in my hands a new book that I wrote. The real thing, and it’s gorgeous. I think this is my 6th book to be published, which kind of blows me away when I stop to think about it, and so far, the thrill of holding a new book that I’ve written hasn’t diminished at all. Every book is its own thing, with its own creative challenges and rewards, so to hold each in its final form brings its own unique thrill. I hope people like this one. As I seem to say with all my books, I’m trying something new, stepping into uncharted story territory. I’m actually working on the sequel at the moment, and I can’t wait for you all to see where the story goes. But I’m getting ahead of myself. THIS book comes out later in the month, and I’ll be having a book launch party at The King’s English, my favorite independent bookstore in the world. Please join me.

The Quantum League Launch Party

A new bio that is not autobiographical.

The following entry comes to you courtesy of a certain commenter to whom I am related. I take no responsibility for its content, and the opinions contained therein do not reflect those of the management, AKA, mine.

I am Matthew’s little sister Amy. His “Short, short bio” is keeping me up at night because it’s so BORING! I decided to take the initiative and re-write it for him, because I’m just that kind of person, and he’s busy being a famous author (“double book launch” and all that).

It should go something like this… Matthew’s ears must have magical powers because he always rubs them for inspiration (and distraction). His childhood was just as rich as any young adult work of fiction. He got spectacular gold rimmed glasses in 6th Grade and compensated in coolness (for the unwelcome addition) by smacking his gum extra loud. Matthew almost became proficient at the piano, but shocked everyone at his last recital (age 14) as he stood up mid-sonata and announced that “he quit.” In spite of that very unexpected drama, he has an amazing ear for music and a decent baritone. He sings loudly in the car, but not in the shower. During his younger days, Matthew’s summers were filled with scout camps, catching fire flies, building forts in the front yard, collecting Batman cards, organizing The Monopoly Clue Club, swimming at the lake, and playing “Adventure Games” in the woods behind his house. He carried a long bow with him in those days, and made trouble using a small cannon equipped with real gun powder and fuses given to him by his Uncle.

Above all, Matthew plays well with others. He is way too charming for his own good. During his adolescence, he dabbled in the fine arts with dreams of becoming a comic book artist or a film director. He enjoys staying up way too late playing computer games with his brother (when he should be writing). He can’t say no to grape Hi Chews, peanut butter and jelly sandwiches on Grandma Sycamore’s white bread, and maple bars with bacon bits (gross!). His mind is like a magnet for fascinating information, unappreciated by most, but necessary for his craft. Much to the credit and appreciation of his younger sisters, Matthew is extremely well versed in classical romance movies such as (but not limited to) Pride and Prejudice, Jane Eyre, Anne of Green Gables, Little Women, and Random Harvest. He is loved by his nieces and nephews. He has a kind perceptive heart, brilliant mind and ever-growing imagination. Icefall is my favorite book. If you haven’t read it, you should. If you have read it, read it again!

So, it’s been a while since I blogged…

In the past eight months or so, I’ve finished three books. The Lost Kingdom (which comes out later this year on September 1st), Cave of Wonders, my installment in the Infinity Ring series (which also comes out on September 1st), and the first book in my Quantum League series (which won’t come out till next spring). This is not a pace I think I could keep up long-term, but it’s been so fun to work on each of the projects. Now I’m working on the first book in my science fiction series with HarperCollins, and it’s a blast, too.

I’ve also done a few events recently. I did a wonderful visit at Saint James School in Montgomery, Alabama (thanks, Benji!), participated in the Children’s Literature Festival at Truman State University, and presented at the conference of the International Reading Association in San Antonio with Matt de la Peña. I’d never been to San Antonio before. Can someone explain the river thing? I mean, was it a real river at some point?


I also got some new author photos taken. The result of which was this:


And this:


Many thanks to the talented Naomi Leu, who took the photos. If you live in the Salt Lake area and you’re looking for a photographer for yourself, your wedding, or another event,  I highly recommend her. (You can find more about her here.)


I’ll be teaching at a few upcoming workshops.

The first will be the midyear workshop of the Florida regional chapter of the SCBWI. You can find out more about that here.

The next will be my Advanced Novel class at the Writing and Illustrating for Young Readers workshop. I’ve mentioned that conference many times here before. It’s the place where I met my agent and got my start. If you’d like to register for my class, or the classes of any of the other amazing faculty members, check it out here.

Rounding out the month of June will be the Jackson Hole Writers Conference. To register and find out more, go here.





Cover reveal! Infinity Ring Book 5: Cave of Wonders

Hi, everyone! I’m really excited to finally share the cover for Cave of Wonders, book 5 in the amazing Infinity Ring series from Scholastic!



This story was a ton of fun to write, even though I had some rather large shoes to fill (namely those belonging to the giant feet of James Dashner, Carrie Ryan, and Lisa McMann, whose first three books in the series are out now, and you should all go read). Cave of Wonders takes Dak, Sera, and Riq to the Golden Age of Baghdad, on the eve of its destruction by Mongols. A truly compelling period in history that I wish more kids knew about. Hopefully, this book will change that for a few of them when it comes out later this year, on September 1st. As I have more details, I’ll post them, but for now, I hope you enjoy the cover!
