This is an epic saga of two Irish cousins who grew up as brothers. Together they share many wondrous and frightful adventures to the different realms of the past, present, and future, along with their cohorts, which include a clurichaun, an Irish wolfhound, and a semicrazed banshee. The story is full of poetry, spells, portents and prophecies, magic, and Celtic mythology. Connor and Finn battle supernatural forces as well as the Morrigan. There are legacies and family secrets, as well as curses, that threaten this clan to its undoing.
