For Grady McClarty, an ever-watchful but bewildered five-year-old boy, World War II is only a troubling, ungraspable event that occurred before he was born. But he feels its effects all around him. He and his older brother Danny are fatherless, and their mother, Bethie, is still grieving for her fighter-pilot husband. Most of all, Grady senses it in his two uncles: young combat veterans determined to step into a fatherhood role for their nephews, even as they struggle with the psychological scars they carry from the war. When news breaks that a leopard has escaped from the Oklahoma City Zoo, the playthings and imagined fears of Grady’s childhood begin to give way to real-world terrors, most imminently the dangerous jungle cat itself.

It is Illinois in the 1830s and 1840s. Abraham Lincoln is a circuit-riding lawyer, a member of the state legislature, a man of almost ungovernable ambition. To his friends he is also a beloved figure, by turns charmingly awkward and mesmerizingly self-possessed. Among his friends and political colleagues are Joshua Speed, William Herndon, Stephen Douglas and many others who have come to the exploding frontier town of Springfield to find their futures. It is through another friend, fictional poet Cage Weatherby, that we will come to know Lincoln in his 20s and 30s, as a series of formative, surprising incidents unfolds.
