The Fathomless Caves (The Witches of Eileanan Book 6) by: Kate Forsyth

After an attack during the Beltane festival the Righ decides it is finally time to take war to the Fairgean. Gathering the first army representative of all the lands of Eileanan he marches to what will be a long war. But unknown to the Righ the Fairgean plan to use the power of the red comet to call a tidal wave that will destroy all life on the land. Can the Righ and the Coven of Witches find a way to stop them?

I was not to fussed with this book there was a lot of the book which I found boring and did not really see the point of. I think it was probably the worst book of the series. I much preferred the sequel series Rhiannon's Ride, which I read first. This series does flesh out character in that and does have a couple of really good books and some really entertaining character.
