On the morning of April 19, 1995, Delaney Travis went to the Alfred P. Murrah Federal Building in Oklahoma City to replace her social security card. Shortly after her arrival, a forty-eight-hundred-pound bomb exploded, resulting in 167 deaths and 684 injuries. This act of terrorism was the deadliest on American soil at that time. Delaney’s boyfriend Keith and her half-sister Edie were devastated. There was no word, no body recovered. The truck she drove was demolished in the rubble and the coat she wore confirms her presence. She just had ceased, The twenty-year anniversary of the tragedy is here. Edie and Keith have married and are still dealing with their grief and lack of closure. Amidst personal and professional pressures, Edie unexpectedly receives a “friend request” on Facebook– from someone posing as Delaney. What sort of hoax is this? What possible motive could anyone have? Could she possibly be alive? And if so, how could she have waited all this time without contacting them? Always insecure about Keith’s feelings for her half-sister, Edie is mortified when she discovers he has also received the request and has hidden the fact from her. To survive as a couple and solve the mystery that has haunted them for two decades, they must confront this and other issues in their relationship. Just as you see the story winding down, a surprising twist is revealed. While it reshapes the narrative, it felt somewhat abrupt and could have been foreshadowed more effectively. Still, it did add a nice dimension to the story. "Low April Sun" uses the Oklahoma City bombing as a backdrop but does not exploit the tragedy. The novel explores themes of addiction, white supremacy, and the controversial issue of fracking and its potential link to earthquakes. Convicted bomber Timothy McVeigh appears as a minor character. Constance E. Squires has written a charged mystery that reminds us of the devastation caused by this heinous crime. The author highlights the suffering of both the victims and the survivors. This is a well-rounded, extremely satisfying read. I received an advance review copy for free, and I am leaving this review voluntarily.
