Unicorns are real. (At least we think they are.) Are you ready to protect the creatures of myth and legend? Then you belong in The Unicorn Rescue Society. HURRY! THE CREATURES NEED YOU! Elliot Eisner isn't exactly thrilled with the first day at his new school. His class is going on a field trip to a creepy forest called the Pine Barrens. The trip is being led by Professor Fauna, the weirdest teacher Elliot has ever met. And the only kid who will talk to Elliot, Uchenna Devereaux, isn't afraid of danger. She likes danger. Elliot and Uchenna are about to become part of a secret group of adventurers, The Unicorn Rescue Society, whose goal is to protect and defend the world's mythical creatures. Together with Professor Fauna, Elliot and Uchenna must help rescue a Jersey Devil from a duo of conniving, greedy billionaires, the Schmoke Brothers.

Elliot and Uchenna have barely recovered from their first adventure with the Unicorn Rescue Society when the mysterious Professor Fauna approaches them with an all-new quest. And this time, they're going to have to cross the Atlantic Ocean to the Basque Country of northern Spain. Elliot and Uchenna, with Jersey in tow, soon wonder whether their newest, fire-breathing rescue might be more than they can handle. And why do the evil-doing Schmoke Brothers seem to be involved yet again?

Among the towering fir trees of the Pacific Northwest, a famously elusive creature is in serious trouble. All Elliot wants is a nice, normal day at school. All Uchenna wants is an adventure. Guess whose wish comes true? Professor Fauna whisks the kids—and Jersey, of course—off to the Muckleshoot territory in Washington, where film crews have suddenly descended en masse to expose Bigfoot to the world, and the Schmoke logging company is bringing in some awfully large machinery. Can the Unicorn Rescue Society escape the blades of the Schmokes' chain saws? Outsmart a cable news team? And are those big, hairy creatures running through the forest really Bigfoot?

The fourth book in the fully illustrated, globe-trotting middle grade fantasy-adventure series about mythical creatures and their cultures of origin, from the Newbery Honor-winning author of The Inquisitor’s Tale. Elliot and Uchennna have only just returned from their most recent Unicorn Rescue Society mission when they (along with Jersey!) are whisked away on their next exciting adventure with Professor Fauna. This time, they’re headed to the Mexican border to help another mythical creature in need: the chupacabras! The Chupacabras of the Río Grande is co-written with David Bowles, author of the Pura Belpré Honor-winning book, The Smoking Mirror!

Critically acclaimed author Emma Otheguy joins Newbery Honor-winning Adam Gidwitz as co-author of the newest adventure in the NYT bestselling Unicorn Rescue Society series as the kids travel to Cuba to help the legendary Madre de aguas. In Cuba, it is believed that a mysterious water serpent—the Madre de aguas—is responsible for providing and protecting the fresh water of the island. But the serpent is missing, and a drought has gripped the island. Uchenna, Elliot, and Professor Fauna fly to Cuba and endeavor to rescue the Madre de aguas. Unfortunately, it tries to kill them. Meanwhile, the Schmoke Brothers' goons are driving around Havana, dumping pink sludge into the sewers. What is going on? Can Elliot and Uchenna end the drought? Stop the Schmokes? Or will the creature they are trying to save just eat them instead?

The newest adventure in the bestselling Unicorn Rescue Society transports readers to the Himalayan mountains in Northern Pakistan! When Uchenna and Elliot's classmate publishes an article in the school newspaper about the Schmoke Brothers, Professor Fauna notices something alarming in a photo. Mounted on the wall of the Schmoke's living room is a single spiral horn that he's certain could have come from only one animal—a unicorn! To save these magical creatures—and to finally see a unicorn themselves—the Unicorn Rescue Society heads to the rugged mountains of Pakistan. Hena Khan, the critically acclaimed author of Amina's Voice, joins Newbery Honor-winner Adam Gidwitz for the Unicorn Rescue Society's most dramatic, action-filled mission yet!
