This was published a year before Artemis Fowl and was reprinted after Artemis became a great hit, for which I can't blame the publishers. It is a story about the Christian afterlife as propagated in story and tale in Ireland for centuries. It has a minion of the devil and a minon of God fighting for the control of a balanced soul. It is a well-used story, showing some age but I enjoyed it.
On the face of it it's obvious that Meg Finn should go to hell. She was involved in a breakin on Lowrie McCall with Belch Brennan and his nasty pit bull Raptor, the outcome of which was Lowrie injured by the dog and Meg, Belch and Raptor dead, because Belch needed to prove his superiority and threaten Meg and accidentally blow them all to bits. When Meg arrives in the afterlife she's balanced between good and evil and gets a chance to go back and earn her way into heaven. She has to help Lowrie. Lowrie decides to make a wish list of things he wishes he had done, and the two of them go to it. Meanwhile Hell send Belch after her.
It's light, predictable, fun and I enjoyed it as a fun diversion.
