The Hadley Academy for the Improbably Gifted

Young readers will find action, suspense, and a perilous battle between good and evil in 
The Hadley Academy for the Improbably Gifted 

from New York Times bestselling author Conor Grennan.

Jack Carlson is dreading a class presentation when he suddenly finds himself transported to the Hadley Academy, a secret institution that tracks teens with unlikely gifts and trains them to protect the world from an unseen squad of killers. But Jack isn't the only one who doesn't know what he's doing at Hadley. Despite indications that he is the one prophesied to end the ancient Reaper War, Jack appears to have no extraordinary abilities.

So when dark, mysterious forces grow, Hadley is in a confused panic. Much to everyone's dismay, humanity seems to depend on Jack and his new teammates. Can Hadley's rawest recruits push past personal struggles and enormous doubts, develop their dormant powers, and stop the spreading evil? And are they willing to commit to Hadley's motto, "One Life for Many," and make the ultimate sacrifice? The Hadley Academy for the Improbably Gifted might be just the place for Jack after all.

This action-packed novel will captivate readers with its riveting plot, relatable characters, humorous dialogue, and dynamic illustrations. Fans of the Hunger Games, the Chronicles of Narnia, Divergent, Maze Runner, and Rick Riordan's books will find themselves at home in the battle for good at the Hadley Academy.

“By the final cliffhanger, readers will be primed for a sequel.” – Kirkus Reviews

Jack Carlson

“I am confident in saying that your book might've been the best book I've read since I read the Harry Potter series. My dad told me to give you an email because I read your book in two days! I would love to see a sequel (although I know the book isn't even out yet). Thanks for writing this awesome book!” 

– Young reader: Joseph Matysik

“For my son’s English class, he had to pick a book and make a book cover. I wanted to show you his illustration and his book recommendation for Hadley Academy. Please feel free to share and keep me in mind for advanced reader copies of other books in this fabulous series!"

Conor Grennan is an author and a crime fighter. He used to live in Kathmandu, Nepal, where he rescued trafficked children and reunited them with their families in remote mountain villages. He wrote a book about those adventures called Little Princes: One Man’s Promise to Bring Home the Lost Children of Nepal, which was a New York Times bestseller.

Conor spent his middle school and high school years in Jersey City, New Jersey, just like Jack Carlson. As a thirteen-year-old, Conor survived his rough neighborhood by dreaming of summer getaways on Monhegan Island, an island off the Maine coast and the model for Elk Island, home of the Hadley Academy. Today, Conor serves as the Dean of Students at the NYU Stern School of Business. He lives in New Canaan, Connecticut, with his wife, Liz, his children, Finn and Lucy, and their dog Beasley in a very ordinary and not-at-all-secret suburban neighborhood. Team Grennan still visits Monhegan Island every summer, hiking through the tall pine forests and helping each other discover gifts they never knew they had.
