Dragon's Honor (Star Trek: The Next Generation Book 38)

DRAGON'S HONOR
Isolated for centuries, the exotic Dragon Empires finally ready to join the United Federation of Planets. But first the emperor's eldest son must marry the only daughter of his oldest enemy, bringing to an end decades of civil war. Without the wedding, there can be no peace -- and no treaty with the Federation.
As honored guests of the Dragon Empire, Captain Picard and the crew of the Starship Enterpriseâ„¢ must ensure that the royal wedding occurs on schedule, despite the Empire's complicated and difficult codes of honor. And Dr. Beverly Crusher finds her loyalties torn when she wins the confidence of the unusually reluctant bride-to-be.
More than just a treaty is at stake, for a vicious race of alien conquerors will stop at nothing, from assassination to invasion, to keep the Empire out of the Federation. Picard must now use all his skills to save the Empire...and preserve the Dragon's Honor.
