Impossible Creatures by Katherine Rundell

“It was a very fine day… until something tried to eat him.” — First line of Impossible Creatures by Katherine Rundell

When Christopher rescues a drowning baby griffin from a hidden lake, he discovers the Archipelago—a secret cluster of magical islands where creatures of legend have lived for centuries. But something is terribly wrong. The magic that sustains the islands is fading, and creatures are beginning to die.

Teaming up with Mal, a determined girl on the run, Christopher sets off on a race across the islands to uncover the truth. Along the way they consult sphinxes, battle kraken, negotiate with dragons, and face dangers that grow darker with every step. As the mystery unravels, it becomes clear that no one else can fix what’s happening. If the Archipelago is going to survive, it will be up to them.

What Worked:

• A Sweeping, Magical World – The Archipelago is richly imagined and bursting with life. From griffins to dragons to kraken, the world-building is immersive and expansive. Each island feels distinct, layered, and alive with history. It’s the kind of setting that makes you want to explore every hidden corner.
• Emotional Depth – This isn’t just a creature-filled fantasy romp. At its core, the story wrestles with loss, courage, responsibility, and hope. There’s a weight to the narrative that elevates it beyond simple adventure.
• A Voice That Hooks You Immediately – The narration is one of this book’s biggest strengths. The very first sentence grabs you and doesn’t let go. There are moments that genuinely make you laugh out loud, even in the middle of high-stakes scenes. Even the Guardian’s Bestiary—an appendix cataloging magical creatures—is written with texture, wit, and humor.

What Didn’t Work:

• Transitions – There were a couple of moments that felt unclear, especially a scene where a boat is stolen and the characters are left in the water, yet suddenly they seem to have their original boat again. It’s possible I missed a detail while listening to the audiobook, but the transition felt abrupt and briefly pulled me out of the story.

Final Thoughts:

Impossible Creatures is a lush, imaginative fantasy that blends myth, adventure, and emotional weight. It delivers high-stakes action alongside genuine heart, and it trusts young readers with big ideas about hope, sacrifice, and responsibility. Although there were a few moments of confusion, the overall experience was magical and immersive. This is a wonderful pick for readers who love expansive fantasy worlds filled with legendary creatures and who don’t mind a little heartbreak along the way.
