Join the Chicken Squad for their many (mis)adventures with the first four chapter books in the hilarious series that has been called “lip-bitingly funny” (School Library Journal) by the bestselling author of Click, Clack, Moo and Diary of a Worm. Dirt, Sweetie, Poppy, and Sugar might be chicks, but they sure aren’t chicken. They’re the Chicken Squad, the barnyard’s best crime fighters. And these chicks are not your typical barnyard puffs of fluff, oh no! They’ve taken on UFOs, led the search for a kidnapped house, traveled deep into the wild, and confronted a mysterious, shoe-napping shadow. Fueled by bravery and jelly beans, no mystery is too big or too small for the Chicken Squad (at least THEY don’t think so).

One of the most famous science books of our time, the phenomenal national bestseller that "buzzes with energy, anecdote and life. It almost makes you want to become a physicist" (Science Digest). Richard P. Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. In this lively work that “can shatter the stereotype of the stuffy scientist” (Detroit Free Press), Feynman recounts his experiences trading ideas on atomic physics with Einstein and cracking the uncrackable safes guarding the most deeply held nuclear secrets—and much more of an eyebrow-raising nature. In his stories, Feynman’s life shines through in all its eccentric glory—a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.

From Pulitzer Prize finalist Annie Jacobsen, the untold USA Today bestselling story of the CIA's secret paramilitary units. Surprise . . . your target. Kill . . . your enemy. Vanish . . . without a trace. When diplomacy fails, and war is unwise, the president calls on the CIA's Special Activities Division, a highly-classified branch of the CIA and the most effective, black operations force in the world. Originally known as the president's guerrilla warfare corps, SAD conducts risky and ruthless operations that have evolved over time to defend America from its enemies. Almost every American president since World War II has asked the CIA to conduct sabotage, subversion and, yes, assassination. With unprecedented access to forty-two men and women who proudly and secretly worked on CIA covert operations from the dawn of the Cold War to the present day, along with declassified documents and deep historical research, Pulitzer Prize finalist Annie Jacobsen unveils -- like never before -- a complex world of individuals working in treacherous environments populated with killers, connivers, and saboteurs. Despite Hollywood notions of off-book operations and external secret hires, covert action is actually one piece in a colossal foreign policy machine. Written with the pacing of a thriller, Surprise, Kill, Vanish brings to vivid life the sheer pandemonium and chaos, as well as the unforgettable human will to survive and the intellectual challenge of not giving up hope that define paramilitary and intelligence work. Jacobsen's exclusive interviews -- with members of the CIA's Senior Intelligence Service (equivalent to the Pentagon's generals), its counterterrorism chiefs, targeting officers, and Special Activities Division's Ground Branch operators who conduct today's close-quarters killing operations around the world -- reveal, for the first time, the enormity of this shocking, controversial, and morally complex terrain. Is the CIA's paramilitary army America's weaponized strength, or a liability to its principled standing in the world? Every operation reported in this book, however unsettling, is legal.
