When Tianna uncovers a mysterious journal linked to the legendary ransom of Emperor Atahualpa by Francisco Pizarro, she and her grandfather are drawn into one of history’s greatest unsolved treasure hunts. During the Spanish conquest of the Inca Empire, hundreds of tons of gold were hidden deep within the treacherous Llanganates Mountains, and never recovered.
Following fragile maps, faded translations, and ancient landmarks, Tianna travels from European archives to the high Andes, where forgotten temples and dangerous terrain guard secrets meant to stay buried. But they are not alone. A powerful enemy is closing in, willing to risk everything to unlock the treasure’s final hiding place.
With her loyal companions Reno and Echo at her side, Tianna must solve the puzzle before the mountains claim another expedition.
Tianna and the Curse of the Llanganates Gold blends real history, thrilling adventure, and clever problem-solving in a breathtaking race against time.

Tianna and the Vanishing Crown Jewels
A royal treasure stolen without a trace. A mystery that baffled detectives, authors, and adventurers alike.
In 1907, the priceless Irish Crown Jewels vanished from Dublin Castle, and nobody knows what happened to them. Despite intense investigation, even offers of help from famed author Sir Arthur Conan Doyle, Sherlock Holmes author, were turned away, and theories involving prominent figures like Robert Shackleton only deepened the mystery.
More than a century later, Tianna Howard uncovers forgotten letters, sealed records, and hidden connections that suggest the truth may have been deliberately buried. Following the trail through historic libraries, private collections, and long-sealed corridors of power, Tianna begins to realize that the disappearance may not have been a simple theft at all, but part of a carefully concealed chain of events stretching across generations.
As new clues surface, so does the unsettling sense that someone else is still guarding the secret. With her grandfather’s guidance, and her loyal companions Reno and Echo at her side, Tianna must piece together the final fragments of the puzzle before the last evidence disappears forever.
Blending real history with clever puzzles and thrilling discovery, Tianna and the Vanishing Crown Jewels invites readers into a gripping royal mystery where fact, legend, and hidden truth collide.
