A legendary sword. A forbidden love. A race against time.

Deep in modern Japan’s shadows, former Navy SEAL Jack Fletcher seeks redemption while brilliant historian Dr Hana Sato fights for her family legacy. Together they must outwit a Yakuza cartel and decode an ancient map to recover the Shogun’s sword, a relic said to channel the spirits of emperors. Their quest will force them to choose between duty and desire, honor and survival, in a high‑octane adventure that blends mystery, romance and Japanese culture.

ABOUT THE BOOK

Deep in the shadows of modern Japan, former Navy SEAL Jack Fletcher seeks redemption for his haunted past. When fate pairs him with brilliant historian Aura Tanaka, their quest for the mythical Sword of the Shogun ignites a dangerous game of survival.

As they scale the treacherous slopes of Mount Fuji, more than just ancient secrets emerge. Ruthless Yakuza gangsters and fanatical nationalists pursue them at every turn, while an undeniable attraction blooms between them—one that could either save or destroy their mission.

With action, rich Japanese culture, and a passionate romance that defies borders, "Sword of the Shogun" weaves a spellbinding tale of two unlikely allies forced to trust each other with their lives... and eventually their hearts.

Perfect for fans of Clive Cussler, Diana Gabaldon, and James Rollins, this thrilling adventure will transport you to a Japan where ancient legends and modern dangers collide. Join Jack and Aura as they race to uncover a treasure that could change history—or cost them everything.
