From the author of the international number one bestseller I Know This Much is True comes a magnificent novel which explores the consequence of violent events, and the chaos that ensues, for human lives blown irrevocably off course Caelum Quirk and his wife Maureen move to Colorado and find jobs at Columbine High School. One day in April 1999, when Caelum is called away by a family emergency, Maureen cowers in a cupboard in the school library, hiding from two students on a murderous rampage. Though miraculously she survives, Maureen cannot recover from the trauma. Seeking solace, the couple returns to Connecticut to an illusion of safety on the Quirk family farm. As Maureen fights to regain her sanity, Caelum discovers a cache of forgotten memorabilia spanning five generations of his family. As he painstakingly reconstructs the lives of his ancestors, he must confront their secrets and fashion a future from the ashes of his own tragedy. His personal quest for meaning becomes a mythic journey that is both contemporary and quintessentially American.
