Imagine a company so big and so powerful that its annual turnover is equal in size to China’s entire GDP. A company whose gross turnover for just one financial year is sufficient to buy at current market value the world’s three largest public companies: General Electric, Royal Dutch Shell and Microsoft. A company that if it dipped into its petty cash could in the same year also buy Coca-Cola. A company where ten days’ turnover is in excess of the combined assets of the world’s top fifty banks.

It exists. Its current annual turnover of more than $500 billion is derived from just three products: heroin, cocaine, marijuana. The drugs cartel of cartels is a factual reality, but sometimes it is only through fiction that one can get close to the real truth.

Drawing on years of experience as a bestselling investigative writer, David Yallop has produced an explosive fiction debut. Unholy Alliance is a breath-taking high-speed race that goes straight to the truth behind the modern American nightmare and into an alarming, but all too believable future.
