Peadar Ó Guilín Books in Order

Stopmouth's tribe survives by hunting other intelligent species and trading human flesh. Betrayal by his brother and the arrival of a mysterious woman from the sky force him to question the brutal world he has always known.

To save his endangered tribe, Stopmouth ventures from the Surface into the Roof, an advanced civilization approaching collapse. Pursued by its authorities, he searches for Indrani, whose knowledge may offer his people a way to survive.

With the Roof collapsing and their tribe under attack, Wallbreaker leads his followers across a hostile wasteland toward a possible refuge. His brother Stopmouth stands at the center of both their hopes for survival and his desire for revenge.

Irish teenagers disappear into the Grey Land, where the vengeful Sidhe hunt them for a day that lasts three minutes at home. Nessa, whose legs were damaged by polio, trains to survive despite others dismissing her chances.

After surviving the Call, Nessa and Anto hope for a life together. Accused of helping the Sidhe, Nessa is condemned to the Grey Land, while Anto joins the fight against an invasion and struggles to rescue her.
