A startling buzzing blasts from your phone or TV, followed by a high-pitched whine, and a detailed description of a missing child inching across the screen. It’s an active Amber alert — a child abduction emergency. We experience these alerts too often, but we rarely learn what becomes of the missing child or how such a disappearance affects the child’s family, friends and the community in which the child lives.

Marybeth Mayhew Whalen’s 10th novel, Every Moment Since, is a fictional exploration of the emotional forces that wear on those who knew and loved 11-year-old Davy Malcor, who went missing for over two decades. The narrative opens with an early morning phone call informing Sheriff Lancaster that Davy’s favorite jacket was found in an abandoned building near the small North Carolina town of Wynotte. The burden of Davy’s disappearance is still very much in the public consciousness, fixed there by a bestselling memoir written by Davy’s older brother, Thaddeus, who had been responsible for watching over Davy on the night he vanished. On that tragic evening, Davy’s parents were attending a cocktail party, and Thaddeus ditched Davy so he could drink beer with his buddies. Davy wandered in the darkness with a mysterious new friend until headlights flickered through the neighborhood and Davy was gone. What happened that night transformed the characters’ lives and, years later, one question haunts them all: What might I have done differently?

Whalen has provided an intriguing cast of characters. Tabitha, Davy’s mother, is divorced (a byproduct of her son’s disappearance) and lives alone in the house where Davy was raised. She devotes her time to advocating for the families of missing children. Thaddeus is profiting from his family’s misfortune with a bestselling memoir. Aniss Weaver, the last person to see Davy alive, works as a public information officer for the local police. Gordon Swift, a local sculptor, is the prime suspect in Davy’s disappearance, although there has never been adequate evidence to bring charges against him. We have all the ingredients for a suspenseful mystery.

But Every Moment Since isn’t your typical whodunnit. The plot is a trifle too straightforward: a boy goes missing, his family suffers, the community agonizes, a body is eventually found, and the mystery, albeit a slight one, is solved. There are too few plot twists or complications in the early stages of the narrative, and much of the expository information in the first 180 pages of the 363-page novel focuses on the minutia of the characters’ day-to-day lives. Throughout the story, there is a nagging need to “bring on the bear.”

Whalen’s focus, the moving force in the novel, is guilt, which the characters suffer to various degrees. Tabitha rebukes herself for having left Davy in Thaddeus’ care so she could spend an evening socializing. Aniss Weaver is troubled by her specific knowledge that Thaddeus is blameless. And Thaddeus, more than any of the characters, is troubled by the financial success of his memoir about his brother’s disappearance. Gordon Swift, although innocent, suffers from doubts about his sexuality and the community’s suspicion that focuses on him as the likely culprit.

Whalen employs various third-person points of view that are not arranged chronologically (think Pulp Fiction). And the chapters range from excerpts taken from Thaddeus’ memoir to Tabitha’s daily bouts of regret to pure narrative segments that nudge the story forward. Even Davy, who has long since disappeared from the immediate action, has a third-person limited view in parts of the novel.

If this sounds like a lot to keep straight, it is, and the reader is required to focus his or her attention on what is happening to whom and when. The only question that needs answering is why the narrative is presented in this disjointed fashion, which becomes apparent in the novel’s final chapters.

The reader might reasonably conclude that the novel was written with the audiobook in mind (available as a digital download through Kindle). Chapters featuring the various personas written in the limited third person achieve degrees of separation and distinction when read by voice actors representing the various characters. For example, book chapters about Tabitha contain too few distinctive hooks that the reader can employ to establish an ongoing connection with the character, and one’s attention must remain fixed on who is doing what and when. Read aloud, the connection is immediate and continuous.

Every Moment Since is not recommended for anyone suffering from ADHD or for casual readers who will likely put the novel aside for days and expect to pick up the narrative line without rereading. The shifting points of view will not detract from the novel’s impact if the reader remains focused.

Whalen creates believable characters and has a true talent for dialogue — and she is to be congratulated for taking on a challenging and complex subject. The disappearance of a child is a horrifying possibility for any parent, and the crippling emotions suffered by a family that has experienced such a loss are almost inconceivable. Every Moment Since is a reminder that we should take careful notice of the Amber alerts that come blaring across our TVs and phones. They aren’t works of fiction.
