Accompanied by the imperious Moon Queen and LOZ 4000, a toenail clipping robot, the First Cat in Space journeys across a fantastic lunar landscape in a quest to save the world.

THE FIRST CAT IN SPACE AND THE SOUP OF DOOM (Book #2)

The Moon Queen has been poisoned—by SOUP.

With few she can trust in her own royal court, she and First Cat will have to journey alone to find the antidote. If only LOZ 4000 were still with them . . . But our once-heroic toenail clipping robot is on the run, looking for new purpose in this vast universe. 

Unbeknownst to our trio, secret forces are working against them. In a world of villainous cowboys, high-speed chases, and falling pianos, can our iconic trio find their way back to one another and save the Moon Queen before it’s too late? And who would want to poison her? Is Captain Babybeard, the adorable baby pirate, in this one? 

THE FIRST CAT IN SPACE AND THE WRATH OF THE PAPERCLIP (Book #3)

Award-winning creators Mac Barnett and Shawn Harris are back with the third volume in the bestselling The First Cat in Space graphic novel series! Prepare to meet an evil paperclip, space dinos, and another adorable bunny. Mac & Shawn also reveal their tried-and-true method of scoring free dessert at restaurants. 

4.5 billion years ago . . . an AI paperclip named CheckMate was designed to fix grammatical errors. Exhausted of correcting "who” vs. “whom,” it concocted a plan to eliminate spelling errors once and for all. All life-forms would be turned into something beautiful, practical, perfect: a paperclip.

Thankfully, it was buried in the debris. Long forgotten . . . until it was accidentally freed. Now CheckMate has invaded every computer on Earth and is bent on fulfilling its dastardly plot. There's only one trio who can save the day: the First Cat in Space, the Moon Queen, and LOZ 4000. But when CheckMate zoops First Cat's spacesuit, our titular hero is now powerless. The fate of the world depends on...a regular little kitty cat. 

Will everyone in the universe become school supplies?!

REVIEWS

Obvious work of creative joy. A definite winner in the age of Dog Man.--Booklist

Barnett is cruising comfortably in his usual lane of quirky humor, and Harris matches the absurdity with cleverly composed illustrations that balance visual humor with narrative necessity. Kids who have graduated from Binky the Cat will be delighted to join another furball on intergalactic adventures.--Bulletin of the Center for Children's Books

Epic lunacy.--Kirkus Reviews

'In full, vivid color, the loose cartoon style exudes an infectious glee, flawlessly matching Barnett’s freewheeling, absurdist humor and plotting.' —Publishers Weekly (starred review)

'Readers looking for the outer space high jinks and gentle humor of Brockington’s Catstronauts and the imaginative and fantastical worldbuilding of Andrews’s This Was Our Pact need look no further than this laugh-out-loud tale of the first cat in space.' —School Library Journal (starred review)

'The surprisingly earnest themes of friendship and individual purpose combined with the absurd humor should resonate with this audience of readers.' —Horn Book Magazine

“A hilarious graphic novel.”  —New York Times
