Sometimes I find my way to GU books via a circuitous route. Awhile back I saw a reference to The Wolves of Willoughby Chase by Joan Aiken and realized it was a classic of children’s literature that I had completely missed, so set out to rectify that. While plucking it off the library shelf, I noticed nearby another book in the series by the same author, called Is Underground. Obviously the “underground” caught my eye, and I was even more excited once I realized that “Is” was the name of the main character, who was therefore a titular girl. So clearly this book had to come home with me too!

I devoured Wolves quickly and enjoyed it a great deal, and it was quite nearly a GU story itself, with a double-protagonist, although ultimately I felt it didn’t quite qualify. Then I moved on to Is Underground. This one is more definitively GU, although sadly it lacks a satisfying final solitary confrontation and defeat of the adversary.

Is, an orphan living with her sister, one day encounters her dying uncle who begs her to search nearby London for his missing son (her cousin). Once there she discovers that many other children are missing, including the king’s own son. After receiving a mysterious invitation to board a train bound for “Playland” and a supposed life of fun in the North, clever Is realizes it must be related and plays along, only to escape before the rest of the children disembark (and are taken directly to a life of slavery working in the mines). She discovers that there is a whole town built underground here, populated by child slaves, evil guards, and somewhat oblivious wealthy adults. She also discovers that she has more distant family members here, who try to help her in her search for her cousin, the king’s son, and some solution to the evil being wrought. Yet another family member, her own uncle, is the Adversary, who has set himself up as a king in this wasteland.

Is eventually ends up voluntarily working with the other children in the mines in order to figure out how to save them. She discovers a hidden talent, as well as a prophecy circulating that seems to indicate she is destined to help. She finds one of the two boys she was looking for, and manages to rescue most of the enslaved kids, with some help. In the end, her Adversary is destroyed, but not directly through her own actions.
