Carson Napier is a pragmatic office worker whose routine is shattered when a mysterious, midnight‑dated letter arrives, urging him to answer a woman in a white shroud. The next night, that spectral figure materializes in his bedroom, delivering a single cryptic line about a man named Guadalupe and a meeting in Guaymas. The uncanny encounter pulls Carson out of his legal paperwork and into a world of secret messages and hidden agendas.
Soon he’s recruited by his old colleague Jason Gridley, who has just intercepted a radio transmission from Pellucidar—the legendary inner world beneath the Earth’s crust. An expedition that once vanished there left a young German officer missing, and rumors now suggest his rescue is possible. As Carson follows the clues, he becomes entangled in a daring plan that could lead him deep beneath the surface, where unknown dangers and ancient societies await.
