A young woman gets more than she bargained for as she strives to unravel her father’s past in Adams’ novel.

The implosion of lives built around carefully kept secrets is one of popular fiction’s most enduring story arcs; that’s the psychological terrain Sofia Ryan finds herself occupying after her father, Aidan Ryan, suddenly vanishes, leaving wads of cash and a stern missive (“I have a new life now and must never see you again”) that sheds no further light on his rationale for making such a move. Fearing that her father has met with foul play, Sofia discovers otherwise after combing through a box of his personal items. She soon realizes that nothing about her father’s backstory as she knows it is genuine, prompting an international trek from Boston to Northern Ireland and Rome in search of answers. At the core of the riddle of Aidan’s past is the Brotherhood, a shadowy religious order (“The stories of their heroic deeds characterize them as a kind of Irish Knights Templar”) with whom Sofia’s father is intimately intertwined for reasons that are murky, at first. If the unexamined life is not worth living, Sofia—finding herself at a harrowing crossroads—comes to realize that an overly interrogated one can be downright murderous. The narrative is founded upon a conceit that built the brands of artists like Dashiell Hammett and Alfred Hitchcock, one that could easily go awry in less adept hands. Happily, that’s an outcome that Adams’ novel deftly avoids by virtue of its no-nonsense pacing and tight plotting—a particularly impressive feat, considering the story skips decades and is liberally sprinkled with flashback fairy dust. Getting the details right, as the author has done, goes a long way toward ensuring an enthralling read. This hair-raising roller-coaster thrill ride may leave readers questioning their own personal narratives.

Secrets and lies collide in this sinisterly effective thriller.
