02 — Books

Two shelves. One fascination: how minds work.

Ciphers, codes, and mentalism for solvers and performers, and a children's line curious about how different minds work. Different readers, the same underlying fascination.

For solvers and performers

Ciphers, codes & mentalism

Secrets, and the minds that keep or crack them.

First release · January 2027

Hidden in Plain Text

A Puzzle Book of Codes and Ciphers, and the People Who Made and Broke Them

Each chapter opens with a secret someone desperately wanted to keep, shows how the cipher worked and how it was eventually broken, then hands you fifteen hidden messages to solve with nothing but a pencil. From Caesar's shift to the book cipher. Every message reveals a true fact, and most have nothing to do with codes.

Paperback, print-on-demand through Amazon. Published by Rependium Press.

Mentalism: routines built on persuasion, not sleight of hand.

Every routine is built on structure, scripting, and psychology instead of finger skill. What little technique is involved is simple. The real skill is pulling it off mid-conversation, not drilling it alone at a mirror for a thousand hours.

The angle nobody else has: routines built on negotiation psychology and lawyerly framing — leading a spectator the way you lead a witness. A cross-examination and a mind-reading routine do the same thing: lead someone to a conclusion they think is their own. Translating one into the other is barely a stretch.

Status

Mentalism titles follow the cipher book, headed for the established magic marketplaces. These are the storefronts working performers already buy from. Titles announced closer to release.

For families

Children's books

Picture books about how minds work.

A children's line about how minds work: logic, puzzles, games, fairness. Sometimes that means a close look at how a different kind of mind takes in the world. Pitched in the gap between ordinary picture books and material written for grown-ups. Deduction as a bedtime story. Rules and fairness a four-year-old can argue about.

Every book is written to be performed and read aloud by tired parents, so rhythm and flow are quality bar number one.

Text quality is the moat

Every book is drafted, read aloud, and redrafted by a professional writer of precise language.

Sold where parents shop

Published print-on-demand through Amazon — paperbacks first, since kids' books are bought as gifts. First titles announced at launch.
