What challenges will they face on this spur-of-the-moment mission to our central star?

For most of Elizabeth Sawin's career, she was not a multisolver. Instead, she worked on a single, albeit immensely important problem: climate change. Despite tremendous effort, she felt like she was chasing her tail. Unless people began to recognize the multitude of unexpected benefits from ratcheting down emissions, climate change would remain a losing political issue.

In 2013, the Toronto Police Service announced that the disappearances of three men—Skandaraj Navaratnam, Abdulbasir Faizi, and Majeed Kayhan—from Toronto's gay village were, perhaps, linked. On January 18, 2018, Bruce McArthur would be arrested on suspicion of first-degree murder, and later sentenced for the murders of eight men. This book tells the complete story of the McArthur murders. Based on more than five years of in-depth reporting, this is also a story of police failure, of how the queer community responded, and the story of the eight men and the lives they left behind.

Cancer may be kicking Warren's a$$, but he's not about to let aliens destroy his home and everything he loves (which is mostly just his dog, Buck). Besides, what does he have to lose? Better to die with sword in hand, bleeding out from a head wound than in some hospital bed...

Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.

The issues of poverty, inequality, racial injustice, and climate change have never been more pressing or paralyzing.

This book draws on stories of committed social changemakers to uncover a set of principles and practices for social change that dramatically depart from the industrial approach. Simple yet profound, these stories distill timely lessons for leaders, scholars, and policymakers.
