“What would happen if Harry met Sally in the age of Tinder and Snapchat? . . . A field guide to Millennial dating in New York City” (New York Daily News). When New York–based graphic designers and long-time friends Timothy Goodman and Jessica Walsh found themselves single at the same time, they decided to try an experiment. The old adage says that it takes forty days to change a habit—could the same be said for love? So they agreed to date each other for forty days, record their experiences in questionnaires, photographs, videos, texts, and artworks, and post the material on a website they would create for this purpose. What began as a small experiment between two friends became an Internet sensation, drawing five million unique (and obsessed) visitors from around the globe to their site and their story. 40 Days of Dating: An Experiment is a beautifully designed, expanded look at the experiment and the results, including a great deal of material that never made it onto the site, such as who they were as friends and individuals before the forty days and who they have become since.

Who was the real King Arthur? What do the historical documents tell us about the Knight of the Round Temple? It is just a chivalric fantasy? The story of Arthur has been handed down to us by Medieval poets and legends - but what if he actually existed and was in fact a great king in the early years of Britain's story. Mike Ashley visits the source material and uncovers unexpected new insights into the legend: there is clear evidence that the Arthurian legends arose from the exploits of not just one man, but at least three originating in Wales, Scotland and Brittany. The true historical Arthur really existed and is distantly related to the present royal family.
