Princeton, 1921. Albert Einstein is touring America, dazzling audiences with the strange new language of relativity. But behind the applause, shadows gather?agents trailing his every step, whispering of "building blocks" and the chance to turn theory into power.

For Max Sterling, Chloe, and Nick, it should have been routine: one more mission to guard a fragile hinge of history. Instead, they uncover a conspiracy to twist Einstein's discoveries into a weapon, and a plot to abduct the world's greatest mind before he can share his vision with the world.

From Ivy League halls to Boston's storm-lashed docks, from fog-bound streets to the decks of steamships bound for Europe, the trio are drawn into a chase that pits them against spies and kidnappers who will stop at nothing to claim Einstein for themselves.

To save him, they devise a desperate plan to spirit Einstein out of the country. If they fail, science's brightest star could be extinguished before its light changes the world?and the future itself may be rewritten in fire.

The Relativity Ruse is a heart-pounding adventure of science, espionage, and history?perfect for fans of fast-paced historical thrillers and the acclaimed Max Sterling Adventures.
