Booklist – October 15, 2011
Proof of Heaven is a remarkable first novel that explores the intersections of science and religion, medicine and faith. Hackett uses a unique blend of scientific terminology and religious history to illustrate Colm and Cathleen’s journey, adding a layer of realism to an incongruous premise. While Cathleen’s maternal trials could have been amplified to melodramatic extremes, Hackett’s lyrical restraint allows the character to shine. Hackett also takes full advantage of her supporting characters, allowing Colm’s newest doctor and Cathleen’s troubled brother to carry portions of the narrative. Reminiscent of Carol Cassella’s recent work, this is an emotionally fulfilling, spiritually inviting, thought-provoking novel.
