Hey fellow demigods! What's up, Camp Half-Blood crew?
I was 13 when I first picked up The Lightning Thief and my life changed. I still lose it every time Percy calls Zeus "Sparky." That snarky, reluctant hero vibe mixed with ancient myths exploding into modern life hooked me instantly, and I’ve been wearing my Camp Half-Blood necklace ever since like it’s actual armor.
Fast-forward a few years and I discovered Suzanne Collins’s Gregor the Overlander. Suddenly I had another questing kid thrust into a hidden underground world full of prophecies, giant creatures, and family stakes that hit way too close to home. It scratched the same itch as Percy’s world but with darker tunnels and even more emotional gut-punches. No wonder so many of you are out here Googling “gregor the overlander similar books” or “Percy Jackson read-alikes.” You’re chasing that perfect blend of fast-paced mythological adventure, hidden realms, and protagonists who actually feel stuff about destiny and loss.
I’ve been on the hunt for years, and I finally struck gold with a fresh 2026 release that feels like it was written just for us. Amelia Moon and the Sundance Shadow by R.J. Roark sits right in that sweet spot. Below I’m breaking down my top 10 recommendations that deliver the same mix of wonder, danger, and heart. Let’s dive in.
Why Gregor the Overlander Still Hits Different for Percy Jackson Fans
Gregor and Percy both get yanked into worlds they never asked for, handed prophecies they don’t want, and forced to grow up fast while worrying about their families. The Underland Chronicles lean grittier and more grounded in nature’s harsh realities, while Percy Jackson amps up the humor and Greek spectacle. Together they create the ultimate blueprint: reluctant heroes, loyal (sometimes sarcastic) friends, and quests that test courage without forgetting the emotional cost. That’s exactly why readers keep searching for more stories that feel like natural extensions of both series.
