Genre: Action & Adventure
Story language: English

What are Leo and Mia like together?: Leo and Mia are siblings who care deeply about each other but turn almost everything into a friendly competition. Leo is protective and organized, while Mia is bold, curious, and usually the first to spot what he has missed. They sometimes argue over who should lead, but they apologize quickly and work best as a team.
What should we know to make Leo feel true to life?: A thoughtful 15-year-old older brother who likes sketching maps, checks every plan twice, and says “We’ve got this” when he is secretly nervous.
What should we know to make Mia feel true to life?: An energetic 9-year-old younger sister who notices tiny details, keeps interesting pebbles in her pockets, and celebrates good ideas with a little victory dance.
Is there a real moment, place, or tiny detail you’d love them to recognize?: One rainy afternoon, they built a blanket fort in the living room using a faded blue blanket and dining chairs. They drew a treasure map on the back of an old grocery list, packed apple slices for supplies, and laughed when Mia knocked over a cup of juice while crawling through the entrance. They still call any especially cozy hiding place “Blue Base.”
Is there a place or kind of world that belongs in their story?: A contemporary coastal town during the school holidays, centered around their apartment, a familiar neighborhood park, a small footbridge, and a quiet beach with tide pools. The places should feel safe and recognizable while still offering room for discovery.
How should the reader feel at the end?: Warm, triumphant, and reassuring. I want both siblings to feel equally important, proud of how they handled their disagreements, and excited to remember the adventure as another shared family story.
Is there anything we must get right—or leave out?: Keep the adventure gentle and age-appropriate, with no serious injury, death, cruelty, bullying, weapons, supernatural horror, or prolonged separation. Any danger should be mild and resolved through teamwork, honesty, and asking a trusted adult for help when needed.
Additional details: Please keep their sibling banter affectionate rather than mean. Leo tends to straighten crooked objects when thinking, while Mia hums when she is concentrating. Include their inside phrase, “Blue Base rules,” and let a slightly squashed apple snack become a small running joke. Neither sibling should be presented as the permanent leader.
