Tempest of Secrets: Sofia Costa Mysteries Book 7

by Georgia Wagner

One missing sister. A typhoon masking a smuggling ring. Ex‑Interpol agent Sofia Costa has forty‑eight hours to dive into Japan’s storm‑lashed underworld before everything—and everyone—she loves goes under.

A desperate text drags Sofia to a remote island battered by a typhoon, where Julian Varga’s marine‑biologist sister Mila has vanished. The only clues are her half‑flooded research hut and whispers that point to a cache of priceless artifacts moving through an underwater exchange point. With the storm intensifying, Sofia and Julian brave treacherous seas, walk the slippery streets of Tokyo’s underworld and descend to shipwrecks where yakuza divers trade stolen art for blood money.

Every lead pulls them closer to the Varga family’s darkest a legitimate foundation bankrolling smuggling operations and Josef Varga, Julian’s ruthless brother, who will protect his empire at any cost. Trapped between corrupt officials and crime lords, Sofia relies on razor‑sharp instincts and Julian’s roguish skills as they infiltrate high‑security clubs and police stations. Amid typhoon‑fueled chases and underwater battles, their friendship threatens to ignite into something more—even as Julian’s life hangs by a thread.

Fans of fast‑paced international mystery thrillers will be swept away by Tempest of Secrets, where atmospheric settings, smoldering tension and intricate conspiracies collide in a race against time.
