Balance of Power is a Star Trek: The Next Generation novel by Dafydd Ab Hugh.

Among the items at auction are medical devices, engineering advances—and a photon pulse cannon capable of punching through a starship's shields with a single shot.

Meanwhile, at the Academy, Wesley Crusher comes to the aid of his best friend—and finds himself kidnapped by outlaw Ferengi bent on controlling the universe through commerce.

When they also set their sights on the photon cannon, Captain Picard must find a way to save the Starship Enterprise and the Federation from the deadliest weapon ever known—with every race in the galaxy aligned against him.

Following Dafydd Ab Hugh's first Star Trek novel, Fallen Heroes, he discovered that he earned more money from writing these types of books than those outside of the franchise.
