Age range 14+  The Borderlands aren't like anywhere else. Don't try to smuggle a phone or any other piece of technology over the wall that marks the Border — unless you enjoy a fireworks display in your backpack. (Ballpoint pens are okay.) There are elves, harpies, and — best of all as far as Elliot is concerned — mermaids. Elliot? Who's Elliot? Elliot is thirteen years old. He's smart and just a tiny bit obnoxious. Sometimes more than a tiny bit. When his class goes on a field trip and he can see a wall that no one else can see, he is given the chance to go to school in the Borderlands. It turns out that on the other side of the wall, classes involve a lot more weaponry and fitness training and fewer mermaids than he expected. On the other hand, there's Serene-Heart-in-the-Chaos-of-Battle, an elven warrior who is more beautiful than anyone Elliot has ever seen, and then there's her human friend Luke: sunny, blond, and annoyingly likeable. There are lots of interesting books. There's even the chance Elliot might be able to change the world. '...A classic school story, a coming-of-age tale and a parody of Harry Potter. It's hilarious and sneakily moving. Elliot Schafer is Harry Potter if Harry had been abandoned instead of merely orphaned. Convinced of his unlovability, he wields sarcasm and braininess as weapons...Brennan subverts the familiar Y.A. love triangle in uproarious, touching, unexpected ways, and her commentaries on gender roles, sexual identity and toxic masculinity are very witty.'  — New York Times Book Review 'Four years in the life of an unloved English schoolboy who's invited to a secret magical school and learns that even in fantasyland, real life is messier than books...But over the course of four years training among child soldiers, Elliot, unsurprisingly, grows up. His slow development into a genuinely kind person is entirely satisfying, as is his awakening to his own bisexuality and to the colonialism, sexism, and racism of Borderlands society...A stellar...wholly rewarding journey. — Kirkus Starred Review 'Amid shifting relationships, the threat of war, and substantial growth among the characters, Elliot's razor-edged wit and general inability to keep his mouth shut make for blissfully entertaining reading. Smart explorations of gender stereotypes, fluid sexuality, and awkward romance only add to the depth and delight of this glittering contemporary fantasy.' — Publishers Weekly Starred Review
