Sunrise on the Serengeti, waiting for the sound of thunder to signal the approaching wildebeest migration, Charlie Hamilton-James is desperately hungover.

This rip-roaring memoir is Fear and Loathing behind the scenes of a big budget wildlife documentary, ‘gonzo journalism’ in the jungle. Eaten alive by insects, sustained on guinea pig meat and cocaine, Hamilton-Jones has lived in the trenches, fighting for the ephemeral perfect shot. But amidst the debauchery and very real danger are moments of transcendence; a chance to see what the rest of the world will have to watch on television. In I Can’t Eat My Guinea Pig, he tells the story of an extraordinary life, lived alongside the advent of modern nature photography and signposted with his most iconic images.
