Order of the Black Sun #22

The Einstein Equation

Rate this book
Belgian physicist Dr. Jacobs learns that an infamous version of the Einstein Equation, thought to have been destroyed, had been discovered by billionaire genius David Purdue. Knowing how deadly the equation’s application would be, he tries to contact Purdue to warn him, but Purdue is frantically busy trying to solve the equation. Little does Purdue know that the Order of the Black Sun is using him to solve the equation for them, to set the ball rolling on a terrible experiment that could cause mass scale destruction.

Having worked on a similar experiment for the Order, Jacobs knows the extent of the damage. In a desperate attempt to expose his Black Sun superiors for planning the mass assassination of world leaders, utilizing his project, Dr. Jacobs looks up renowned journalist Sam Cleave and gives him an exclusive interview. When the Order finds out, they kidnap Jacobs’ girlfriend, Olga, to lure him out and keeps her captive on the Valkyrie, a trans-Siberian train heading for a terrible end.

In an attempt to free Olga, Jacobs, Nina and Sam soon realize that they are racing against the genius of Purdue’s inadvertent solution.
Once solved, the Einstein Equation will be applied to accelerate the runaway train to a deadly speed, fulfilling a devastating experiment and killing all on board. Now they are aboard the hypersonic threat with no way to stop it, unless they can undo the threat of the Einstein Equation.

Vulgarity ruins

There is no way to say it politely, I love the Preston Child novels, but the use of vulgar words ruins the story. It didn't add to the story, it wasn't necessary to develop the characters, it was just a way, in my humble opinion, to distract & degrade a great author's body of work.

MOVING ALONG

Good read, nice plot, and a few twists and turns. Characters are consistent with previous novels. Would recommend this series only for the Adventure that lurks in you.

Not his best story, but entertaining anyway!

There are a LOT of word usage and spelling mistakes in this one. The way of ending the story was MUCH better than normal for this author though. Much improved!

GOOD read. Since this is the last book in this series. What is next since this book did not appear to end the series. Everyone is still alive and well?
