New Hampshire entrepreneur and investor Sean Dempsey has released a new personal finance book that challenges conventional wisdom about saving, investing and building long-term wealth. “Financial Cheat Codes: How to Win the Game of Finance” presents what Dempsey describes as a “road map to financial security,” drawing on strategies he has used in his own business and real estate ventures. Dempsey frames his approach through an extended video game analogy, describing “cheat codes” as overlooked strategies that can accelerate financial success when properly understood and applied. The 200-page book features multiple full-color, video-game-themed illustrations designed to make complex financial concepts more accessible. Dempsey will sign copies of the book on Saturday, Feb. 7, at Toadstool Bookshop in Peterborough.
