The Book of Three
written by Lloyd Alexander
part of The Chronicles of Prydain

The Foundling and Other Tales of Prydain is a collection of six short stories (newer copies including eight) by Lloyd Alexander. Although first published in 1973, after the five novels that comprise The Chronicles of Prydain, these short stories take place before the events of the books that preceded them.

The Black Cauldron is the second book in Lloyd Alexander's five-part novel series The Chronicles of Prydain (first published in 1964). The story centers on the adventures of Taran, an Assistant Pig-Keeper in the magical land of Prydain, as he joins in a quest to capture the eponymous vessel, a magical device which can be used to create armies of the undead.

The Castle of Llyr is the third volume in the children's fantasy series Chronicles of Prydain. Taran continues his adventures and encounters new friends and old enemies. The book is mostly lighthearted although the final scenes add depth and substance to Taran's character.

Taran Wanderer is the fourth book in the Chronicles of Prydain series by Lloyd Alexander. It tells of Taran's search for his lineage through which he encounters many different people who each help to shape Taran as he learns about who he truly is. It is the only book in the series in which Princess Eilonwy does not appear, though she is referenced frequently. It is also the only book in the series in which Prince Gwydion does not appear.

The High King is the last book in the Chronicles of Prydain fantasy series of books by Lloyd Alexander. Taran and the Companions join the rest of Prydain in a final struggle to defeat Arawn at great cost.
