Small Mercies is thought provoking, engaging, enraging, and can't-put-it-down entertainment. -- Stephen King

The acclaimed New York Times bestselling writer returns with a masterpiece to rival Mystic River--an all-consuming tale of revenge, family love, festering hate, and insidious power, set against one of the most tumultuous episodes in Boston's history.

In the summer of 1974 a heatwave blankets Boston and Mary Pat Fennessy is trying to stay one step ahead of the bill collectors. Mary Pat has lived her entire life in the housing projects of Southie, the Irish American enclave that stubbornly adheres to old tradition and stands proudly apart.

One night Mary Pat's teenage daughter Jules stays out late and doesn't come home. That same evening, a young Black man is found dead, struck by a subway train under mysterious circumstances.

The two events seem unconnected. But Mary Pat, propelled by a desperate search for her missing daughter, begins turning over stones best left untouched--asking questions that bother Marty Butler, chieftain of the Irish mob, and the men who work for him, men who don't take kindly to any threat to their business.

Set against the hot, tumultuous months when the city's desegregation of its public schools exploded in violence, Small Mercies is a superb thriller, a brutal depiction of criminality and power, and an unflinching portrait of the dark heart of American racism. It is a mesmerizing and wrenching work that only Dennis Lehane could write.

From the creation of the first encyclopedia to Wikipedia, from ancient museums to modern kindergarten classes--this is award winning writer Simon Winchester's brilliant and all-encompassing look at how humans acquire, retain, and pass on information and data, and how technology continues to change our lives and our minds.

With the advent of the internet, any topic we want to know about is instantly available with the touch of a smartphone button. With so much knowledge at our fingertips, what is there left for our brains to do? At a time when we seem to be stripping all value from the idea of knowing things--no need for math, no need for map-reading, no need for memorization--are we risking our ability to think? As we empty our minds, will we one day be incapable of thoughtfulness?

Addressing these questions, Simon Winchester explores how humans have attained, stored, and disseminated knowledge. Examining such disciplines as education, journalism, encyclopedia creation, museum curation, photography, and broadcasting, he looks at a whole range of knowledge diffusion--from the cuneiform writings of Babylon to the machine-made genius of artificial intelligence, by way of Gutenberg, Google, and Wikipedia to the huge Victorian assemblage of the Mundanaeum, the collection of everything ever known, currently stored in a damp basement in northern Belgium.

Studded with strange and fascinating details, Knowing What We Know is a deep dive into learning and the human mind. Throughout this fascinating tour, Winchester forces us to ponder what rational humans are becoming. What good is all this knowledge if it leads to lack of thought? What is information without wisdom? Does Rene Descartes's Cogito, ergo sum--I think therefore I am, the foundation for human knowledge widely accepted since the Enlightenment--still hold?

And what will the world be like if no one in it is wise?
