The Warriors series meets Redwall in this first book in an epic animal adventure series set in the subway tunnels of Brooklyn.

Hopper is just an ordinary pet shop mouse before he escapes. Soon he finds himself below the bustling streets of Brooklyn, deep within the untamed tangles of transit tunnels, and in Atlantia, a glorious utopian rat civilization.

But all is not what it seems. Though Hopper is treated as a royal guest, he misses his siblings that he lost in the escape attempt. That, and Atlantia is constantly threatened by the rebels who wish to bring the city to its knees. And there are cats everywhere in Atlantia, cats that leave the citizens unharmed… and no one can seem to answer why.

Soon, Hopper is caught in the crosshairs of a colossal battle, one that crosses generations and species. As the clashes rage, Hopper learns terrible, extraordinary secrets: Deadly secrets about Atlantia. Painful secrets about his friends.

And one powerful secret about his destiny…

Editorial Reviews

Publishers Weekly
Sword-wielding rats, feline palace guards, and rebel mice fill this adventure with imagination and heart. Hopper, his daring sister, and timid brother are pet store mice. After nearly becoming reptile fodder, the siblings are separated, and Hopper lands in the scary subterranean world of New York City’s subway system. A streetwise rat named Zucker—who turns out to be prince of an empire called Atlantia—saves Hopper from getting clocked by a train. Mouse and rat team up and are soon entangled in a war between the Romanus (who Zucker’s father rules) and the rebellious, mysterious Mus. Hopper is an entertainingly unlikely hero, and Fiedler’s (Romeo’s Ex) villains are suitably nasty, though minor inconsistencies might bother some readers: sheltered Hopper is clueless and alarmed when he meets his first cricket yet has no trouble identifying swords and quickly masters the “metal monsters” of the subway. For those who love an underdog and some romping good battles, Fiedler thoroughly entertains. Art not seen by PW. Ages 8–12. Author’s agents: Susan Cohen, Writers House, and Madeleine Morel, 2M Communications. Illustrator’s agent: Shannon Associates. (May)
"Captivating and cunning, Mouseheart is the next great adventure. Mouseheart is the first in the series which promises to deliver grand adventure and great storytelling. Hopper is one little mouse who roars! Readers who loved Jacques' Redwall series and Hunter's Warrior series will love this new series."
"The underground world and mix of intrigue, prophecy, and betrayal bring to mind Suzanne Collins’ Gregor the Overlander series....Fans of Brian Jacques’ Redwall Abbey series may enjoy this modern adaptation of rodent politics and warfare."
Children's Literature - Elizabeth Fronk
How can Hopper, a small and timid mouse, be the Chosen One? He escapes from a pet store with his bolder sister, Pinkie but loses his smaller brother, Pup. Hopper has memories of his mother telling him to find the “mews.” Pinkie and Hopper get lost in New York and fall into a sewer. Hopper awakens alone but meets Zucker, a worldly rat. They encounter Firren, a female rat and her fellow warrior rats. As Zucker and Hopper continue on their journey, they see a carving that bears a striking resemblance to Hopper—a mouse with a white circle around the right eye along with the inscription, “MUS.” Is this what Hopper must find? Upon arriving in Atalantia, Hopper meets Lord Titus and learns the MUS is evil and an enemy, which confuses Hopper. Hopper remains confused until Firren takes him to the Mus and opens Hopper’s eyes. Hopper learns that Zucker is a close friend of Dodger, Hopper’s father. Hopper’s tale has echoes of Brian Jacques’ “Redwall” series with its small hero, questions about allegiance and discovering one’s heritage. This galley copy shows only some of the illustrations; more detailed illustrations can only add more appeal. Readers may be slightly disappointed with loose ends; these might be answered in the future volumes about Zucker and Hopper. Reviewer: Elizabeth Fronk; Ages 9 to 13.
Kirkus Reviews
A naïve mouse discovers his true mettle when he's accidentally plunged into a world of warring rats, mice and feral cats in Brooklyn's underground transit tunnels. An avowed coward, Hopper lives in a pet-shop cage with his sister and brother. After a dramatic escape, Hopper's separated from his siblings and finds himself alone and terrified in dark tunnels, from which a wily rat named Zucker rescues him. Sympathetic and engaging, Zucker takes Hopper to the sprawling rat metropolis of Atlantia, where Zucker's father, Titus, rules. Treated like royalty and initially impressed, Hopper gradually discovers that Atlantia hides dark secrets. When he's captured by a band of rebel rats who deliver him to a tribe of mice called the Mus, Hopper learns he may be the son of Mus' legendary leader and could indeed be their Chosen One, destined to lead them against their archenemy, Titus. Unsure if he should trust his friend Zucker or the Mus, a confused Hopper resolutely overcomes his fear to discover the real meaning of courage. Riddled with surprises, the fast-paced, complex plot features a host of vivid, memorable rodent and feline characters. Black-and-white illustrations capture key events. Another stalwart mouse with a brave heart will win fans in this captivating underground adventure. (Animal fantasy. 8-12)
School Library Journal
Gr 4–8—Fiedler reinvigorates the "small but courageous mouse" literary trope with this captivating animal fantasy set in the subway tunnels of modern-day Brooklyn, NY. Hopper escapes from a pet shop and tumbles into the subterranean rat empire of Romanus. Aided by his new friend Zucker, rascal prince of the rat empire, he longs to find his missing siblings and understand his role in a war between Romanus and the mysterious Mus tribe. Good and evil are not as they seem, and through careful structure and rounded characterizations, Fiedler keeps readers engaged, revealing important plot details at just the right moment and using varying sentence lengths to great dramatic effect. Rich vocabulary and sly references to New York sports history (Dodger, Ebbets, Rangers) add depth. Older readers may pick up on hints about government control and the dangers of trading freedom for safety. In the end, the stage is amply set for book two as Hopper seeks to reunite with his found-yet-lost-again siblings and explore his destiny as the rodent world's "Promised One." Mouseheart will please fans of novels by Erin Hunter, Brian Jacques, and Kathryn Lasky.—Marybeth Kozikowski, Sachem Public Library, Holbrook, NY

    A great book.

    This was a good book. A little confusing, but very interesting and good details. I can't wait for the second one to come out!
