The idea

Ten worlds. Five stories in each. Fifty stories in total, all in the same valley.

One world, one thing

Every world is about a single thing. Not about feelings in general, but about a bounded skill a child is actually in the middle of building: waiting for something they want. Settling a worry that grows at bedtime. Noticing who is being left out. Telling the truth when it costs something. Trying again after it went wrong.

Keeping a world to one idea is what lets the stories stay small and warm. Nothing has to be explained twice, and nothing has to carry more than one thought.

Characters who come back

Each world has its own characters, and they return. A child who has read a story about Ruby comes back to Ruby, not to a new stranger.

It is the same mechanism that makes children watch the same film again. Recognition lowers the threshold, and a lowered threshold is exactly what makes a difficult subject approachable.

Read them in any order

The stories are entirely standalone. No character travels between worlds, and no story assumes another has been read.

That means a grown-up can start exactly where the child is right now, rather than where a series happens to begin. It is built that way on purpose.

Fifty stories, released one at a time

Fifty stories are written. They're released one at a time, when each one is ready. The worlds are here now — the titles arrive as they're finished.

Hollowdale

Ten worlds, one valley, and a single thread of water running through all of them.

A spring rises in the forest at the top of the dale. It becomes a stream, then a creek, then a brook running past the cottages, widens out across the farmland, and reaches the sea at two places along the coast.

Which means the water a hedgehog clears of litter high in the pines is the same creek a rabbit lives beside further down, the same brook a fox crosses on her way to the market, and the same sea an otter finally learns to swim in. None of the stories point this out. A child who has read two of them notices anyway — and that quiet click, these are all the same place, is the whole reason the dale exists.

No character ever crosses from one world into another, and no story depends on another. What connects them is geography and water, never plot. That is what lets you start anywhere.
