When Gabriel's immigrant mother returns to her native Uruguay, he takes a break from his uninspiring job to accompany her. Immersed in his squabbling family, birdwatching in the wetlands on their abandoned ranch, and falling in love with a local biologist, he makes discoveries that force him to contend with the environmental cataclysm of his turn-of-millennium present--even as he confronts the Cold War-era ideologies and political violence that have shaped his family's past.
