Ilsa J. Bick's What Remains is a gripping narrative that intricately weaves together themes of loss, redemption, and identity. The novel is a compelling exploration of how the past relentlessly shadows the present, and how the truth is often more complex than it appears. Bick, known for her ability to craft intense and emotionally charged stories, does not disappoint with this latest offering.

The story begins with John Worthy, a man haunted by the death of his lover, Roni Keller. His journey to reclaim her remains is not just a physical quest but a symbolic one, representing his need to find closure and peace. This task, however, is complicated by the sudden appearance of Daniel Driver, a former Marine Raider with a murky past. Driver's proposition to John is one that he cannot refuse, setting the stage for a narrative filled with tension and moral ambiguity.

One of the novel's most striking aspects is its exploration of the theme that "the past isn’t dead." Bick delves into how past actions and decisions continue to influence the present, often in unexpected ways. This theme is personified in the character of Daniel Driver, whose past as a Marine Raider and current role as a shadowy operative blur the lines between heroism and villainy. Driver's character is a testament to Bick's skill in crafting complex, multifaceted characters who defy easy categorization.

Similarly, the character of Poya Durrani adds another layer of depth to the narrative. Poya's story is one of survival and deception, as he navigates the treacherous landscape of the Wakhan Corridor. His father's death and the betrayal by his father's handler leave Poya in a precarious position, forced to maintain a facade to ensure his survival. The revelation that "the boy, Poya, is a lie" underscores the novel's exploration of identity and the lengths one must go to protect it.

Bick's writing is both evocative and precise, capturing the emotional turmoil of her characters while maintaining a taut, suspenseful narrative. Her portrayal of the Afghan landscape is vivid and immersive, providing a stark backdrop to the unfolding drama. The novel's pacing is expertly handled, with each chapter building on the tension and intrigue established in the previous one.

In terms of character development, Bick excels in creating protagonists who are deeply flawed yet profoundly human. John Worthy's journey is one of redemption and self-discovery, as he grapples with his grief and the moral complexities of his situation. His interactions with Driver and Poya are fraught with tension, yet they also reveal the underlying humanity that connects them all. Bick's ability to portray these nuanced relationships adds a layer of emotional depth to the narrative.

The novel's exploration of truth and deception is particularly compelling. Bick challenges the reader to question the nature of truth and the extent to which it can be manipulated. This theme is mirrored in the characters' struggles, as they navigate a world where appearances are often deceiving and trust is a rare commodity.

Comparatively, What Remains shares thematic similarities with works by authors such as John le Carré and Graham Greene, who also explore the murky world of espionage and the moral ambiguities inherent in it. However, Bick's focus on personal redemption and the emotional impact of her characters' journeys sets her work apart, offering a fresh perspective on familiar themes.

Overall, What Remains is a masterfully crafted novel that combines elements of thriller, drama, and psychological exploration. Ilsa J. Bick has delivered a story that is both thought-provoking and emotionally resonant, leaving a lasting impact on the reader. For those who appreciate complex narratives and richly developed characters, this book is a must-read.

In conclusion, What Remains is a testament to Bick's prowess as a storyteller. Her ability to weave together intricate plots and compelling characters makes this novel a standout in the genre. It is a story that will linger in the minds of readers long after the final page is turned, a haunting reminder that the past is never truly gone and that truth is often more elusive than it seems.
