Meet the Sithe. They are fairies who cross from the otherworld to ours. But they are not the milksop Victorian variety. They are Celtic fey - violent, capricious, battle-hardened, bloodthirsty, life-loving and definitely randy. So when Seth and his brother end up in 16th century Scotland, things get more than a bit out of control. And if you think the Sithe are bad, there are always the Lammyr to prove that you are mistaken.
