Roughing it in the Bush is the compelling true story of pioneer Susanna Moodie’s experience immigrating to Canada with her sister, Catharine Parr Traill, in the 1830s. Moodie’s narrative is a frank, sometimes humorous, portrayal of life in the Canadian wild, capturing the physical demands of homesteading and the complex personal relationships between settlers.

Initially conceived as a “guide” for British subjects considering immigrating to Canada, Roughing it in the Bush is part of a trilogy that also includes Flora Lyndsay and Life in the Clearings, and continues to inform and inspire Canadians about what life was like at the birth of a nation.

“It is possible to invent a single machine which can be used to compute any computable sequence,” twenty-four-year-old Alan Turing announced in 1936. In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same.
 
Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars.
 
Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.
 
How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

Now, as the espionage community begins to pack up and an apprehensive city prepares for the grim realities of postwar life, Leon is given one last routine assignment. But when the job goes fatally wrong—an exchange of gunfire, a body left in the street, a potential war criminal on his hands—Leon is plunged into a tangle of intrigue, shifting loyalties, and moral uncertainty.

Played out against the bazaars and mosques and faded mansions of this knowing, ancient Ottoman city, Leon’s conflicted attempt to save one life leads to a desperate manhunt that ultimately threatens his own survival. How do you do the right thing when there are only bad choices to be made?
