In Defense of Food

Michael Pollan

Michael Pollan examines why modern eaters became more confused as nutrition advice multiplied. The book asks whether health is best pursued by tracking nutrients or by returning to recognizable foods, cultural knowledge, ecological relationships, and dietary patterns. It ends with flexible guidance for shopping, cooking, sharing meals, and eating mostly plants in moderation.

In Search of Excellence

Tom Peters & Robert Waterman

Why do some large companies keep innovating and performing when rational plans, controls, and scale alone fall short? In Search of Excellence identifies eight connected practices and explains how they turn ordinary work into adaptive, sustained performance.

In the Garden of Beasts

Erik Larson

Through William E. Dodd, his daughter Martha, and their circle in Berlin, this book asks how dictatorship became ordinary to people who could see its violence yet still enjoy its social world. It traces political misreading, institutional complicity, moral awakening, and the limits of diplomacy.

In the Realm of Hungry Ghosts

Gabor Maté

Why do people return to behaviors that harm them, and what can make change possible? Gabor Maté connects addiction with pain, brain development, learned patterns, relationships, and social conditions, then considers compassionate care, harm reduction, and recovery practices. The book offers a framework for understanding compulsion while preserving responsibility and hope.

Incognito

David Eagleman

Incognito asks how much of thought, perception, choice, and identity is authored outside awareness. It connects constructed experience, unconscious learning, competing neural systems, biology, and law to show why the self feels more sovereign than it is—and how that shift reframes responsibility and self-understanding.

Indistractable

Nir Eyal

Indistractable asks why attention slips from chosen goals and how people can reclaim it. It explains the roles of internal discomfort, timeboxed values, external cues, and precommitments, then applies the framework to workplace culture, parenting, and intimate relationships—offering a practical way to protect attention in social settings.

Influence

Robert Cialdini

Influence examines why people say yes, how six psychological shortcuts turn favors, commitments, crowds, liking, authority, and scarcity into compliance, and when those shortcuts fail. Its value is a practical way to recognize manipulation while preserving the cooperation and efficient judgment these social rules normally support.

Inner Engineering

Sadhguru

Inner Engineering asks how people can find steadier well-being and freedom when experience is shaped within, not guaranteed by external conditions. Sadhguru frames yoga as experiential inner work, connecting responsibility and attention with the body, food, thought, devotion, and energy. The ideas offer a practical framework for inquiry, alongside cautions about limits and discipline.

Inspired

Marty Cagan

How do technology teams discover products customers value while meeting business needs? Marty Cagan connects team organization, product strategy, and continuous discovery. The book explains how to frame problems, test ideas, interpret customer evidence, and build a culture accountable for results.

Invisible Women

Caroline Criado Perez

How does treating men as the default shape everyday life? Caroline Criado Perez examines gender data gaps in transport, work, technology, medicine, economics, and government. The book shows how missing evidence becomes unequal provision—and how better measurement, design, and participation can expose and correct these failures.

Isaac Newton

James Gleick

James Gleick traces how Newton moved from childhood observations and self-directed study toward a mathematical account of motion, light, and gravity. The biography follows his unsettled experiments, theological and alchemical inquiries, disputes over priority, and public authority. It asks what mathematical laws explain—and what Newton left unresolved—framing scientific discovery as both proof and unfinished argument.

It Starts with the Egg

Rebecca Fett

Rebecca Fett asks how egg quality, sperm, and conditions around conception shape the chance of pregnancy—and which factors may be changed. The book explains fertility testing, chemical exposures, supplements, diet, embryo transfer, and causes to investigate after setbacks, offering practical decision frameworks alongside limits in the evidence.

It's Not You

Ramani Durvasula

How do harmful narcissistic relationships undermine self-trust, and what helps people recover? Ramani Durvasula explains patterns of manipulation, attachment, and self-blame, then explores acceptance, grief, boundaries, and rebuilding identity. The focus is on practical recovery, including when family, work, or other constraints make continued contact necessary.

It's OK That You're Not OK

Megan Devine

Megan Devine asks how people can live with devastating loss when grief cannot be fixed. She challenges stage-based expectations and hollow comfort, then offers ways to meet grief with self-compassion, practical care, creative expression, boundaries, and honest companionship—without requiring recovery to mean returning to a former self.

John Adams

David McCullough

David McCullough’s biography follows John Adams from a New England farm through revolution, diplomacy, the vice presidency, the presidency, and retirement. It asks how private discipline, marriage, constitutional design, and political independence shaped a statesman—and what war, faction, slavery, and defeat revealed about republican ideals.

Just Kids

Patti Smith

Just Kids follows Patti Smith and Robert Mapplethorpe from childhood through poverty, creative partnership, separation, divergent careers, and illness. It asks how two people can help each other become artists without outgrowing their bond, and how memory, objects, photographs, and songs preserve a life when the person is gone.

Just Mercy

Bryan Stevenson

Just Mercy follows Bryan Stevenson’s work with condemned people, children, women, and others caught in America’s punitive justice system. It asks how race, poverty, trauma, and fear turn vulnerability into guilt, and what proximity, legal advocacy, mercy, and hope can do to restore dignity when formal justice fails.

Justice: What's the Right Thing to Do?

Michael J. Sandel

Michael J. Sandel’s Justice asks how to decide what people owe one another when welfare, freedom, equality, desert, virtue, and loyalty collide. Moving through competing theories and hard cases, it shows why fair institutions require public reasoning about human purposes and the common good, not only calculation or choice.
