Vikings in Ireland (Hardcover)

After making the shortlist for the United States Olympic Team in Dressage in 1975, but not making the Team itself, she turned to writing historical novels exploring her Celtic roots. Her first book was THE WIND FROM HASTINGS, published by Houghton Mifflin Co. in 1978 in the U.S. and subsequently by Robert Hale in London. The book sold well in both hard and soft cover, and she was soon hard at work on her second novel the one for which she will always be remembered LION OF IRELAND: THE LEGEND OF BRIAN BORU, was published in 1980 and has never been out of print since. Combined worldwide hard and soft cover sales figure in the millions. Ronald Reagan invited Morgan to the White House and to his Inauguration, during which he paraphrased her words in LION. The many months she spent in Ireland painstakingly researching every aspect of Brian's life and culture combined with the dramatic story of an unforgettable man to make a novel everyone wanted to read.

Her next book was THE HORSE GODDESS, reconstructing the lives of the early Celts in the Austrian Alps, circa 77 B.C. THE HORSE GODDESS was a Book of the Month Club selection, was given the Novel of the Year Award by the American League of Penwomen, and the paperback rights were sold to Pocket Books for a quarter of a million dollars.

Next came BARD: THE ODYSSEY OF THE IRISH, which told the story of the Milesians and earned for Morgan the 'Woman of the Year' Award from the IrishAmerican Heritage Committee, which was presented to her in New York by then mayor Ed Koch.

Morgan then accepted a commission to write a nonfiction biography of Xerxes of Persia for City College of New York, which was published as THE SUN RISING. Her next novel, written during the period when her husband Charles was dying of cancer, was entitled GRANIA, and is the story of Granuaille.

Moving to Ireland, she subsequently wrote ON RAVEN'S WING, which is the retelling of the Ulster Cycle, published by Wm. Heinemann in the U.K. and by Wm. Morrow in the U.S. under the title RED BRANCH. Next came DRUIDS, the story of the battle for Gaul told from the Celtic point of view, instead of Julius Caesar's. These books, like all her others, have been published in both soft and hardback, and in various translations. Her most recent adult novel is THE LAST PRINCE OF IRELAND, published in 1992 by Wm. Morrow in the U.S. and in the U.K. by Wm. Heinemann (as O'SULLIVAN'S MARCH)

In 1990 Morgan Llywelyn turned to writing for the young reader, with the publication of BRIAN BORU, Emperor of the Irish, a biography in the novelistic style, by The O'Brien Press, Dublin. For this book she won an Irish Children's Book Trust BISTO Award in 1991. Her second book for the young reader is STRONGBOW, The Story of Richard and Aoife (The O'Brien Press) 1992, for which she won a BISTO AWARD in the Historical Fiction category, 1993 and the Reading Association of Ireland Award, 1993. Her third novel for young readers,entitled STAR DANCER, (The O'Brien Press) was drawn from her experience of the world of showjumping and dressage.
