Paul Yoon’s new novel, “Etna,” follows a haunted, battle-scarred war veteran who wants desperately to go home. He also happens to be a dog — a mixed-breed shepherd trained to sniff out bombs for an unnamed military in the throes of an unnamed conflict — and he has no idea where he is anymore, or if his old farm is even still standing after so much violence. Undeterred, he ventures into the great unknown, to somehow find his way back. The result is a powerful story about survival, the brutal cost of war and what it means to step forward after calamity. On this episode of the Book Review Book Club, the host MJ Franklin discusses the novel with his colleagues Elisabeth Egan and Scott Heller.
