Like the rest of Lloyd Alexander’s Chronicles of Prydain novels, The Castle of Llyr is full of adventure, fantasy, and fun. Unlike the previous three, however, Princess Eilonwy is narrowly featured, as is much of the humor we’ve come to know and love. While still present, the peril of Eilonwy—who is kidnapped in the novel—coupled with Taran’s realization that she is to be betrothed creates a more somber presence throughout the book. Without Eilonwy’s clever commentary, the silly—and often profound—similes we expect from her are also absent. (Spoilers ahead.)

The novel is nonetheless as enjoyable as the other three, and necessary in the five-part series. It helps to further establish the growing feelings that Taran has for Eilonwy—as well as vice versa, though not as peppered throughout the book. It also helps fulfill some of the mystery surrounding Eilonwy’s past, and like all of the other books, depicts Taran as he slowly continues to become a man.

Taran’s main source of contempt in the book—aside from Achren, Eilonwy’s aunt and kidnapper—is the annoying, clumsy Prince Rhun. Not only is Rhun constantly in need of assistance lest he fall off a ship, get lost in the woods, or harm himself (as well as others in the process) otherwise; he also is supposed to marry Princess Eilonwy. Both of these characteristics make Taran extremely reluctant to not only put up with the prince, but to also fulfill the king’s request in keeping the boy safe.

Like Taran has previously discovered, however, things are not always as they seem, and he comes to admire the young prince after he selflessly offers to die for the group at the hands of a giant—and then comes to their rescue whenever Taran refuses his sacrifice and saves him instead. Though the prince continues to blunder through the novel—especially when foolishly revealing a secret to Achren herself—he is still redeemed, reminding Taran to keep an open mind.

Eilonwy, who suffers memory loss at the hands of Achren, also makes Taran’s heart weary, as she claims to not know him at all. Once restored, it is evident how much she cares for him back. Achren’s fall—and the forgiveness her would-be capturers give to her—mark another step in Taran’s journey toward manhood and heroism. It’s one thing to conquer and kill; it’s another to be merciful and humane, he learns.

Alexander’s saga is one of the most enjoyable fantasy series available for both young and older readers alike. Though The Castle of Llyr is my least favorite so far, it remains a fantastic adventure worthy of many a read. We also meet a huge enchanted cat who takes a liking to Fflewddur Fflam, sure to be another favorite character in the last two books.
