It’s a murder mystery on the moon in this humorous and suspenseful space adventure from the author of Belly Up and Spy School that The New York Times Book Review called “a delightful and brilliantly constructed middle grade thriller.” Like his fellow lunarnauts—otherwise known as Moonies—living on Moon Base Alpha, twelve-year-old Dashiell Gibson is famous the world over for being one of the first humans to live on the moon. And he’s bored out of his mind. Kids aren’t allowed on the lunar surface, meaning they’re trapped inside the tiny moon base with next to nothing to occupy their time—and the only other kid Dash’s age spends all his time hooked into virtual reality games. Then Moon Base Alpha’s top scientist turns up dead. Dash senses there’s foul play afoot, but no one believes him. Everyone agrees Dr. Holtz went onto the lunar surface without his helmet properly affixed, simple as that. But Dr. Holtz was on the verge of an important new discovery, Dash finds out, and it’s a secret that could change everything for the Moonies—a secret someone just might kill to keep...

In 2041 twelve-year-old Dashiell Gibson's a resident of Moon Base Alpha, and at the moment he's faced with a number of problems: coping with the nasty Sjoberg twins, finding out how the commander of the base has managed to disappear from a facility no bigger than a soccer field, and dealing with the alien Zan, who communicates with him telepathically from afar--and who's hiding a secret which may threaten the whole Earth.

A New York Times bestselling series. Tensions are running high when multi-billionaire Lars Sjoburg is poisoned and everyone is looking to Dash Gibson to solve the case in this third and final book in the New York Times bestselling Moon Base Alpha series. Moon Base Alpha was supposed to be an exciting place to live, but Dashiell Gibson didn’t expect for it to be this exciting. He’s already had to solve a murder and locate a missing moon base commander. Now, he just wants to have a calm, quiet thirteenth birthday. But, of course, trillionaire (and total pain) Lars Sjoburg ruins it—by being poisoned. Now there’s another potential killer loose on Moon Base Alpha, and Dash is forced to identify the most likely suspects. Suddenly Dash finds himself with a target on his back. Whoever poisoned Lars will stop at nothing to keep his—or her—identity a secret.

12 year old Theodore "Teddy" Roosevelt Fitzroy has got a murder on his hands and trouble on his tail. Henry, the hippopatamus at the brand-new nationally known FunJungle, has gone belly up. Even though it's claimed he died of natural causes, Teddy smells something fishy and it sure ain't the polar bear's lunch. Dealing with the zoo's top brass proves to be nothing but a waste of time. They want to see any trace of Henry's death disappear like yesterday's paper. So Teddy sets out to find the truth. With the help of Summer McCraken, a fiesty girl with secrets of her own, the two narrow down their prime suspects. Is it Martin Del Gato, FunJungle's head of operations who hates kids and hates animals even more? Or J.J McCraken, the owner of FunJungle and and hates animals even more? Or J.J McCraken, the owner of FunJungle and Summer's father, who has more concern for the dough he's raking in than the animals in the zoo? As their investigation goes on, Teddy gets squeezed on all sides to quit asking questions or Henry won't be the only animal in the zoo to turn up dead. The deeper Teddy and Summer get, they had better make sure they want to know what they want to know because when it comes to hippo homicide, the truth can't be kept in a cage!
