What I Should Have Known by R.L. Atkinson is a compelling journey through the intricacies of self-discovery and emotional growth. Atkinson delves into the complexities of relationships, the pain of regret, and the power of forgiveness with a sensitivity and depth that is both engaging and profoundly moving. This book, though fictional, provides insights that resonate deeply with anyone who has ever looked back on their life choices and wondered "What if?"

The narrative follows the protagonist, Emily Hart, as she navigates the aftershocks of a tumultuous breakup that leaves her questioning the foundation upon which her life had been built. Set against the backdrop of picturesque Asheville, North Carolina, Emily’s story is one of confronting uncomfortable truths and searching for a path forward amidst the debris of broken dreams.

Atkinson's prose is sharp and evocative, capturing the essence of Emily's turmoil with striking clarity. Each chapter peels back layers of her past, revealing secrets and lies that had long been buried. The author’s ability to intertwine past and present is seamless, weaving together threads that build a tapestry of Emily's life, highlighting both the beauty and the scars.

One of the most striking aspects of Atkinson’s writing is her character development. Emily Hart emerges not merely as a figure of sympathy but as a beacon of strength and resilience. Through her eyes, readers experience the bitterness of betrayal and the salve of deep, meaningful connections. Supporting characters are equally well-crafted, from the steadfast best friend who offers both a shoulder to cry on and tough love, to the enigmatic new acquaintance who challenges Emily to see the world—and herself—in a new light.

The thematic core of the book revolves around the idea that understanding one’s past is crucial to navigating the future. Atkinson challenges the reader to consider how the shadows of past experiences can shape our decisions, often without our conscious awareness. The narrative is punctuated with moments of introspection that are as philosophically rich as they are emotionally charged. Furthermore, Atkinson adroitly addresses the universal quest for happiness and the sometimes painful journey that pursuit entails.

A particularly poignant part of the book is when Emily visits her old family home. Here, Atkinson masterfully uses setting as a metaphor for memory and lost time. As Emily walks through the empty rooms, the readers feel her isolation and her aching nostalgia for a past that was far from perfect but irrevocably hers. This scene starkly highlights the theme of reconciliation with one's past to foster growth.

However, it’s not just a story of heartache. What I Should Have Known is imbued with hope. It is about finding light in dark places and mending oneself with the threads of old ties that bind. Atkinson does not shy away from the messiness of human emotions, yet she offers a lens of optimistic realism. The dialogue between characters is natural and compelling, providing small doses of wisdom in the midst of everyday conversation.

The pacing of the book is another of its strengths. Atkinson knows just when to reveal a secret or introduce a twist, keeping the reader engaged and invested in Emily's journey. The transitions between the tumult of emotional revelations and the tranquility of reflective moments are handled with a finesse that speaks to Atkinson's skill as a storyteller.

In essence, What I Should Have Known is more than just a novel about the aftermath of a failed relationship. It is a study in human resilience, the complexity of human relationships, and the endless capacity for renewal that defines the human spirit. Readers of contemporary adult fiction who appreciate a story that pairs emotional depth with genuine character arcs will find much to admire here.

To conclude, R.L. Atkinson's What I Should Have Known is a beautifully crafted novel that offers insightful reflections on the pain and beauty of looking back and moving forward. It is a testament to the strength required to embrace one's past, warts and all, and to use it as a stepping stone towards a more enlightened self. This book not only entertains but also enlightens, making it a worthwhile addition to any bookshelf.
