Series numeration from Fantastic Fiction.

"Jack Taylor has finally escaped his violent life in Galway for a quiet retirement in the country. But on a day trip back into the city to sort out his affairs, Jack is hit by a truck in front of Galway's Famine Memorial, left in a coma but mysteriously without a scratch on him. When he awakens weeks later, he finds Ireland in a frenzy over the so-called "Miracle of Galway." People have become convinced that the two children seen tending to him are saintly, and the site of the accident sacred. The Catholic Church isn't so sure, and Jack is commissioned to help find the children to verify the miracle or expose the stunt. But Jack isn't the only one looking for these children. A fraudulent order of nuns needs them to legitimatize its sanctity and becomes involved with a dangerous arsonist. Soon, the building in which the children are living burns down. Can they escape?"-- Provided by publisher.
