This is book number 17 in the Cotton Malone series.
King Ludwig II of Bavaria was an enigmatic figure who was deposed in 1886, mysteriously drowning three days later. Eccentric to the point of madness, in the years before he died Ludwig engaged in a worldwide search for a new kingdom. One separate from Bavaria, a place he could retreat to and rule as he wished. But a question remains: Did he succeed?
Enter Cotton Malone. Luke Daniels, Malone’s Magellan Billet protégé, has managed to infiltrate a renegade group on the trail of a 19th century deed that proves Ludwig’s long-rumored search bore fruit. A document that could not only secure Bavaria’s independence, but also change the balance of power in the modern world. The United States, China, and Germany all want it.
In a race across Bavaria for clues hidden inside Ludwig’s three fairytale castles, Cotton and Luke battle an ever-growing list of deadly adversaries all intent on finding the last kingdom.
"What continues to amaze me about the Cotton Malone books is how Steve Berry can consistently find global stories about legendary loopholes or unwritten history that I am completely unaware of . . . Berry is in very limited company when it comes to thrillers of this magnitude, which includes those written by the likes of Brad Meltzer, Brad Thor and James Rollins. This series never disappoints!"—Bookreporter.com
