Don’t miss Elizabeth Wein’s stunning new novel, Stateless Before Verity . . . there was Julie. When fifteen-year-old Julia Beaufort-Stuart wakes up in the hospital, she knows the lazy summer break she'd imagined won't be exactly what she anticipated. And once she returns to her grandfather's estate, a bit banged up but alive, she begins to realize that her injury might not have been an accident. One of her family's employees is missing, and he disappeared on the very same day she landed in the hospital. Desperate to figure out what happened, she befriends Euan McEwen, the Scottish Traveler boy who found her when she was injured, and his standoffish sister, Ellen. As Julie grows closer to this family, she witnesses firsthand some of the prejudices they've grown used to-a stark contrast to her own upbringing-and finds herself exploring thrilling new experiences that have nothing to do with a missing-person investigation. Her memory of that day returns to her in pieces, and when a body is discovered, her new friends are caught in the crosshairs of long-held biases about Travelers. Julie must get to the bottom of the mystery in order to keep them from being framed for the crime. This exhilarating coming-of-age story, a prequel to the Printz Honor Book Code Name Verity, returns to a beloved character just before she first takes flight.

A Turing Award-winning computer scientist and statistician shows how understanding causality has revolutionized science and will revolutionize artificial intelligence "Correlation is not causation." This mantra, chanted by scientists for more than a century, has led to a virtual prohibition on causal talk. Today, that taboo is dead. The causal revolution, instigated by Judea Pearl and his colleagues, has cut through a century of confusion and established causality -- the study of cause and effect -- on a firm scientific basis. His work explains how we can know easy things, like whether it was rain or a sprinkler that made a sidewalk wet; and how to answer hard questions, like whether a drug cured an illness. Pearl's work enables us to know not just whether one thing causes another: it lets us explore the world that is and the worlds that could have been. It shows us the essence of human thought and key to artificial intelligence. Anyone who wants to understand either needs The Book of Why.
