1888. Hawaii. A man with a broken leg lies in a hut on the slopes of Mauna Loa, watching the volcano through a telescope and communicating with his brother by mirror signals flashed across the mountain in Morse code. Tom Hesselgrave is a British scientist conducting fieldwork for the British Association Seismological Committee, and he intends to observe the lava lake with or without the blessing of the local Hawaiians. But the islanders warn him away: the volcano belongs to Pélé, goddess of fire, and she does not tolerate intruders. When Tom befriends Kea, a half-caste girl preparing for a mysterious wedding, he finds himself caught between the cold demands of scientific observation and something far older and more dangerous than geology. Grant Allen's novel is a remarkable period piece, colonial adventure filtered through the lens of emerging scientific materialism confronting a living spiritual tradition. The title itself is a provocation: what does it mean for Western man to plant his foot on sacred ground, to measure and claim what has been worshipped for centuries? The result is a gripping story of volcano, culture, and the cost of certainty.
