Janus Origin: Red River Secrets

by Daniel A. Riddle

They came to find the truth. Instead, they brought the danger with them.

Nathan, Lan, and their closest allies travel to Vietnam on a desperate find Lan's mother, Nhi, and uncover the secrets buried within the Janus Origin Project. The streets of Hanoi hold more than answers. Old loyalties fracture. New alliances form in the shadows. And not everyone in the group has come for the same reason.

As the group pushes deeper into the truth behind Lan's origins, they discover that the conspiracy didn't end in England. It followed them. And Lan's past isn't just catching up with her. It's still lurking inside her head.

With a baby on the way and enemies closing in, Nathan and Lan's relationship begins to crack. Lan questions whether her feelings for Nathan were ever truly hers. New temptations test both their resolve. Trust frays. Betrayal festers. And by the time the group reaches the ancient city of Hue, nothing will ever be the same again.

Some secrets are buried for a reason. And some people will stop at nothing to keep them that way.

Janus Red River Secrets is the second book in the Janus Origin series. A gripping thriller that trades the grey of London for the heat, noise, and chaos of Vietnam. A world that swallows them whole. From the back alleys of Hanoi to the banks of the Perfume River, nothing is what it seems, and no one walks away unchanged.
