And Dr. Basu, Colm’s kind physician, has lost a son of his own and readily understands Cathleen’s grief: “He wanted to reach out, to envelop (Cathleen and Colm) both and promise him that he could make it all better, but he could not.” His benevolent skepticism about heaven connects him to Colm.

For his part, Colm worries about how to tell his devout mother of his spiritual doubts — and that before he dies he wants the chance to meet his father, who abandoned Cathleen years before.

Hackett deftly limns these characters with a few well-chosen strokes, and the narrative carries us along. An adjunct English professor at the University of Cincinnati, she explains in an engaging afterword how she developed the idea for her book. Like her character, as a child and young woman she experienced fainting spells so serious that they eventually led  her to get a pacemaker. And like Colm, as a child she was pious but not at all sure that she believed in God.

No wonder her novel’s description of Colm’s thoughts about going to church rings true: “Church was such a letdown for Colm, and the worst part of it was sitting still. Colm believed his mother and uncle chose to take him to the world’s longest Mass – with a choir that sang every response, with a priest who seemed to go on and on during the homily and who talked with his mother after every Mass. Colm didn’t get it. Why did people come to church? What was the point?”

“Proof of Heaven” is a solid debut novel that will engage readers as it inspires them to weigh the basic questions of why we are here, what it means and what hope may be found in the tale of a child’s suffering.
