Sharon Lee and Steve Miller - Liaden Universe 1 - 12

The Liaden universe (/liːˈeɪdɛn/lee-AY-den or /liːˈeɪdən/) is the setting for an ongoing series of science fiction stories written by Sharon Lee and Steve Miller. The series covers a considerable time period, some thousands of years in all, although since it also covers more than one universe the exact chronology is unclear.

The series is set at some unspecified time in the future. There is a reference to the planet named "Terra" not being the first planet to bear that name; however, the familiar names and cultural references in the core books (coupled with a lack of them in the "Crystal" books) suggest that it is "our" earth nonetheless. In the wake of a diaspora from a "decrystallizing" galaxy that was mankind's prior home, the human race is divided into three major sub-races: Terran, Liaden and Yxtrang. (There are also numerous isolated colony planets that have backslid technologically and are held as protectorates until their civilizations regain enough advances to cope with extraplanetary contact.)

The seven-book "Agent of Change" sequence tells of the struggle between Clan Korval, a Liaden Clan of much note, and the mysterious "Department of the Interior".
The eighth novel, Balance of Trade, is set 275 years prior to the end of the "Agent of Change" sequence. It features Jethri Gobelyn, a young Terran trader who is adopted by a Liaden Master Trader to the consternation of virtually everyone.
The ninth novel, Crystal Soldier, published in February 2005, takes place even earlier still: it is the first half of "The Great Migration Duology", and tells the story of Cantra yos'Phelium, who piloted the original exodus to Liad, and her partner Jela. The sequel, Crystal Dragon, was published in 2006 and takes the story up through the founding of Liad and of Clan Korval.

Agent of Change: Fleeing the scene of his latest mission, Val Con yos'Phelium finds himself saving the life of ex-mercenary Miri Robertson, a young Tarren on the run from interplanetary assassins. Thrown together by circumstances, Val Con and Miri struggle to elude their enemies and stay alive without slaying each other-or surrendering to the unexpected passion that flares between them.

Conflict of Honors: In the second novel of the Liaden Universe, Priscilla Delacroix is betrayed and abandoned by her shipmates. But confronting the crew will be far easier-and safer-than confronting the demons of her past.

Carpe Diem: On the run from interplanetary assassins, covert operative Val Con yos'Phelium and former mercenary sergeant Miri Robertson end up stranded on a distant planet-with no rescue in sight.

Plan B: The Department of the Interior-a secret Liaden agency-has declared war on Clan Korval. With Val Con yos'Phelium still a fugitive, it falls on his cousin Shan yos'Galen to invoke Plan B-the code name of clan's strategy to defend itself in the face of an all-powerful enemy.

Local Custom: The fifth book in the Liaden Universe tells a rich and sweeping story of warring families and star-crossed lovers in a fantastic, other-world galaxy.

Scout's Progress: A novel in the Liaden Universe-the story of a young girl who has won a starship, but now must learn to fly if she is to escape her dastardly brother.

Mouse and Dragon: Aelliana Caylon has endured much, and finally, she appears to have won all: a spaceship, comrades, friends -- and the love of a pilot she adores. But even happy endings sometimes show a few flaws. Such as Aelliana's home clan being not as agreeable to letting her go as it had first seemed.
