Bestselling authors Elizabeth Hamilton-Guarino and Dr. Katie Eastman release powerful new guide to help individuals cultivate hope, healing, and harmony in a world that needs it more now than ever
PORTLAND, Maine, April 21, 2026 /PRNewswire/ — At a time when the world feels increasingly divided, uncertain, and overwhelmed, a new book is offering a timely and deeply needed message: peace is not something we wait for, it is something we practice daily.
Bestselling authors and global peace advocates Elizabeth Hamilton-Guarino and Dr. Katie Eastman announce the release of The Peace Guidebook: How to Cultivate Hope, Healing, and Harmony for the Good of Humankind, publishing April 21, 2026 by Health Communications Inc and Simon & Schuster – available now for pre order on major retail platforms.
With a powerful foreword by Rev. Mpho A. Tutu van Furth, the book opens with a compelling invitation to reimagine peace not as a distant ideal, but as a living, breathing presence in our daily lives.
“This book is a call to action and a call to calm. It is a reminder that peace begins within each of us. Every person matters, every voice has value, and no one has to walk this journey alone,” says Elizabeth Hamilton-Guarino and Dr. Katie Eastman.
A Practical Guide for Real Peace in Real Life
In The Peace Guidebook, Hamilton Guarino and Eastman challenge the belief that peace is passive or only possible during calm moments. Instead, they present peace as an active, daily practice, one that can be cultivated through grief, change, burnout, and uncertainty.
“Peace is not the absence of pain, it is the presence of alignment,” stated authors Elizabeth Hamilton-Guarino and Dr. Katie Eastman. “It is how we live with grace, even when things fall apart.”
The book introduces ten transformational principles, including Presence, Patience, Partnership, and Perseverance, alongside practical tools, real life stories, and guided exercises to help readers integrate peace into their everyday lives.
Peace in Action: From Personal Practice to Global Movement
The Peace Guidebook is part of the broader Percolate Peace Project, a global initiative aiming to inspire one million people to embrace peace as a way of life.
“This is more than a book,” the authors emphasize. “It is a call to action, a blueprint for personal and collective transformation.”
