Walt and Judy, of 1970s small-town Vermont, can't conceive a child. For all their mutual tenderness, life has become just "a collection of gestures and habits". So they adopt.
Specifically, they adopt an orphaned chimpanzee.
Yes, it's a jolting concept, and it means you can't read McAdam's third novel without feeling perceptions shift and conventions splinter.
Looee is from Sierra Leone, his mother killed by a poacher's shotgun blast; his own first months passed as an object of black-market smuggling. The adoption means initial salvation for him, and a challenging journey into courage and sacrifice for his human foster parents.
Right from the start there are people who scream, sneer, talk behind hands at the house's sweet, nutty smell, or who openly denounce Looee as an abomination.
