"Colfer . . . strings dazzling displays of high tech, heartwarming peeks at the family dynamics of the closely knit if decidedly eccentric Fowl clan, dolphin-back rides, huge blobs of slime (some of it explosive), and a climactic exhibition of prejudice gone off the rails. More high-octane Fowl play."--Kirkus Reviews
"Colfer's clever spin-off of the Artemis Fowl series focuses on Artemis Fowl's twin younger brothers--hyperintelligent Myles and near-feral Beckett, both 11. Colfer's trademark tongue-in-cheek narrative voice is on full display, his characters existing in a preposterous balance between sincerity and absurdity, mad science, and technology. Tthis series opener is accessible and entertaining: the fast-paced plot, filled with unexpected betrayals, death-defying feats, and secret train cars, will appeal to Fowl readers established and new."--Publishers Weekly (starred review)
"Fans of the Artemis Fowl novels will not be disappointed with this first novel of the spinoff series. Colfer's razor sharp wit and fast-paced writing will keep readers engaged, entertained and grinning at the puns. High tech spy gadgets blend sci-fi elements to this fantasy novel."--School Library Connection
"Like its bestselling progenitors, a nonstop spinoff afroth with high tech, spectacular magic, and silly business."--Kirkus Reviews (starred review)
"Make way for a new generation of Fowl adventures and fans."--Booklist
