About this book
Moonlight falls on a still pool, and ancient ruins become the threshold of something human reason cannot measure.
Dr. Walter Goodwin trusts evidence, instruments and logic. Then his friend Dr. David Throckmartin brings him a mystery from Nan-Matal, the huge stone ruins on Ponape in the Caroline Islands. Throckmartin’s expedition does not return whole. His wife Edith’s fate gives the men a reason to act, and the ruins draw them back.
Goodwin joins Irish adventurer Larry O’Keefe in a search that leads beyond the familiar world. The Moon Pool opens onto a realm beneath the earth, lit by something other than the sun. In Abraham Merritt’s science fiction adventure, a scientist’s careful account meets strange light, growing dread and people whose world challenges everything he knows.

A path of moonlight races toward the ship
At Port Moresby, Goodwin boards the Southern Queen for Melbourne. On the pier he spots Throckmartin, an old friend and a gifted scientist. A few weeks earlier Throckmartin left to study the ruins of Nan-Matal with his bride Edith, his colleague Dr. Charles Stanton and the nurse Thora Halversen. Now his face holds a strange union of ecstasy and despair.
That night the clouds part and the moon lays a gleaming lane across the sea, running straight at the ship. Far along it comes something opalescent, lit from within, with seven small lights above it. A sound like tiny glass bells rolls over the water.

A botanist, Dr. Goodwin, follows a lost friend's trail to ruined islands in the Pacific. A moon door leads him, an Irish airman and a sailor into a hidden land ruled by a priestess and a creature of living light.
Who is the Dweller in the Moon Pool?
The Dweller, also called the Shining One, is a being of light with seven glowing orbs that rises from a pool under moonlight. It draws people into its embrace and marks them with joy and terror at once.

No. It is a work of fantasy and science adventure by Abraham Merritt, framed as a scientific report. The ruins of Nan-Matal on Ponape are real, but the hidden land and its beings are invented.
