The futureis leaking.

2201. The Year of the Void. The network has gone silent. Before the dark, humanity optimized itself into extinction. We sold our senses to train the algorithms. We rented our nerves to lend "authenticity" to machines. We archived our souls in cold titanium shells to escape the rot of mortality.

Now, through the silence, something is getting through.

22 voices. 22 puzzles. 2 possible futures. One of them will be yours.

ECHO, The Chronicles of 2201. Book cover: the word ECHO in stencil letters split by a thin vertical beam of light over a silent city.

22 voices from 2201

A decrypted archive of 22 human and post-human voices, all of them silenced in 2201. They crossed the fourth dimension, the only barrier future technology ever managed to fracture, to reach the one era that can still hear them. Yours.

They don't explain. They speak in fragments, in riddles, in glitches. Each Echo is a short story and a puzzle at the same time.

"Pain is not an error message. It's a compass."

How the book works

  1. Read the Echo. Two pages of story: a testimony from 2201.
  2. Solve the puzzle. A double-page challenge built from that story. Logic, observation, memory, imagination, deduction, folding the page, reading through mirrors.
  3. The answer is the key. No codes, no lookup tables. Whatever you uncover, word or number, is exactly what you type into the decoder to unlock the next transmission.
  4. Rebuild the message. After the 22 Echoes comes the finale: 22 more pages, one for each Echo, that bring every answer back.
  5. Choose the future. The book has two endings. The one you read depends on you.

the book is complete on its own. both endings are printed inside it.

Every story and every puzzle is written by the two of us. Every illustration starts as a drawing by hand. We use AI the way the book suggests: as a tool that sharpens our work, never as a replacement for it.
