About the Book


Marcus Webb, a modern financial educator, is sent back to 1852 Mississippi. He teaches wealth principles to enslaved men and women who cannot use them because their internal thermostat, the set point for what they believe is possible for people like them, has never been touched.

He fails. He returns. He goes back and works differently, going identity-first with both the enslaved and the enslavers.

When he returns to the present, America looks like the Constitution intended.

The book is for every reader who has ever had the tools and not used them, and never understood why.

The Reader Edition


Buying direct gets you more than the retail edition. The Reader Edition carries the full text of the novel plus a working section built to be used, not admired.

  • The Field Card — the whole book compressed to one page
  • The 30-Day Application Track — four weeks of specific work, one week per phase
  • The Working Pages — audit questions with room to write, built to be used

Read the story straight through first. Then go back and work the pages. The book is the input. The working section is where it becomes yours.
