In his Author’s Note at the beginning of The Black Cauldron, Lloyd Alexander notes that “a darker thread runs through the high spirits” of this second novel in the Prydain series as compared to the first book, The Book of Three. The first book sent Taran, Assistant Pig-Keeper, on a quest to find the lost Hen-Wen and brought him to face the evil Horned King, servant of the Lord of Annuvin. This book involves another quest, darker indeed, to capture and destroy the Black Cauldron, birthplace of the deathless Cauldron-born warriors who also fight for Arawn, Lord of Annuvin. This journey is harder and longer and more perilous than the search for Hen-Wen, and Taran must face sacrifice, hardship and even death itself in his quest to end the power of the Black Cauldron.

But still there is Gurgi with his “smitings and bitings” and Fflewddur Fflam with his harp and Eilonwy, the girl with the sharp tongue and the golden bauble. And “good old Doli” joins the quest, reluctantly, to lend a bit of invisible help. New friends, or perhaps enemies, are Ellidyr, Prince of Pen-Larcau, and Adaon, Son of Taliesin. This second book in the Prydain series really picks up the pace of the story, and readers gain more insight into the characters of Taran and his companions and friends. The Black Cauldron is better than The Book of Three, which is a good book in its own right. That’s as it should be: in a series the books should get better, or else what’s a series for? Alexander writes in the Author’s Note, “[W]hile extending the story, I have also tried to deepen it.”

You can read The Black Cauldron as a stand alone book, but the books in this five book series are better read in chronological and publication sequence. The Prydain books, in order, are:

• The Book of Three
• The Black Cauldron
• The Castle of Llyr
• Taran Wanderer
• The High King

The stories are inspired by Celtic and Welsh mythology, but they don’t follow any one folk tale or myth closely. Prydain is an imaginary realm, not Wales, and the characters in the book may remind one of Celtic heroes, but they are filtered through and created by Mr. Alexander’s imagination, illuminated by Celtic heroes. It’s a lovely set of stories.
