Echo Blue: A Riveting Thriller Involving an Environmental Conspiracy Leading from South America to the Middle East

By Mark Mannock

Are you safe?

Nicholas Sharp receives a mysterious phone call from brother-in-arms, Jack Greatrex... then Greatrex disappears.

The ex-Marine sniper turned musician follows a trail from the jungles of South America to the mountains of Northern Spain and eventually the corridors of power behind the wealth of the Middle Eastern oil supply chain.

Alongside radical eco-activist, Captain Deagan Jones from the notorious Crimson Wave, Sharp uncovers a conspiracy where environmental sabotage and mass human suffering collide. And when Jones' son is kidnapped, the cost of failure becomes personal.

With the stakes never higher, Sharp fights to prevent an environmental and humanitarian catastrophe with unimaginable consequences.

Somewhere between Clancy's Jack Ryan and Ludlum's Jason Bourne, Nicholas Sharp may be a flawed hero, but you certainly want him on your side.
