Fantasy Adventure Book For Preteens

I’m ready to turn a fantasy-filled adventure concept into a polished children’s book that resonates with readers aged 9-12. The tone should feel exciting yet age-appropriate, following a relatable main character who steps into a vividly imagined world, faces meaningful challenges, and grows along the way.

Here’s what I need from you:
• An outline that maps the full arc of the story, chapter by chapter, before drafting begins.
• A complete manuscript written in clear, engaging language suitable for middle-grade readers (target length and chapter count can be finalised together once we review the outline).
• Memorable side characters, well-paced action, and a fantasy setting that sparks curiosity without overwhelming young readers.
• Two short revision rounds after I provide feedback so the final draft is publication-ready.

If you have experience crafting middle-grade fantasy, know how to balance suspense with humour, and can deliver clean, well-edited prose, I’d love to collaborate. Please share a brief note on your approach and any relevant writing samples so we can dive straight into this adventure.
