Ken Flint is obviously a student of Celtic mythos, especially Irish myths, and here he delivers a solid tale of the beginnings of Lugh of the Long Arm. All of the Celtic gods show up here as regular characters, which the implication (completely unspoken) that through the years they were turned into gods by their descendants. A lot of mythology (Greek, Roman, Celtic, Norse, etc.) likely started that way.
Anyway, this first of three books follows the struggles of Lugh to become the champion of the de Dannan peoples and lead them to victory over the hated Fomor people, commanded by the evil and awesome Balor of the One Eye. The books are an interesting blend of fantasy and science fiction. While the de Dannon people fight with swords and spears and use magic while living a relatively simple life in stone and wood huts, the Fomor are quite the opposite. The "lower" Fomor are those afflicted with some knd of genetic hereditary affliction, turning them into monsters. At the beginning of the books, they live on the island Eire (an old name for Ireland, by the way) and are overlords of the subjugated de Dannan race. But we find out that there is another kind of Fomor, these live in a modern tower made of glass, complete with working elevators, and routinely use engine-powered ships, tanks, and other forms of transportations. This is where Balor lives.
Lugh leads the de Dannons against these awesome foes, in a way fighting two battles at once. One is the open rebellion against the lower Fomor and their king Bres on the island Eire. The other is a more covert war against the puppeteers, the "high" Fomor in the Tower. The story is well-written and peopled with interesting characters not common to fantasy literature. Flint does a good job of catching our interst and bringing the old Celtic myths to life in a lively story that at the same time is derived from the Irish myths, yet not slavishly devoted to them. Well worth the effort to find this book, and I highly recommend it.
