At the heart of the story is Doyle, an immortal warrior burdened by a tragic past that has left him emotionally closed off for centuries. His character is a compelling study of resilience and vulnerability, as he grapples with the weight of his history while being drawn to Riley, an archaeologist with a fierce spirit and a connection to the wild.

Riley's journey of self-discovery is particularly poignant; she must confront her practical nature and embrace her feelings for Doyle, which adds depth to her character and highlights the theme of love as a transformative force.

The setting of Ireland plays a crucial role in the story, with its rich history and enchanting landscapes serving as a backdrop for the guardians' quest. Roberts' vivid descriptions transport readers to the rugged coast of Clare, where the past and present intertwine. The incorporation of Irish mythology and folklore adds an additional layer of intrigue, making the quest for the Star of Ice not just a physical journey but also a spiritual one. The dark goddess that the guardians face is a formidable antagonist, representing the chaos and destruction that can arise from unchecked ambition and power. This conflict underscores the importance of unity and the strength found in relationships, as the guardians must rely on one another to overcome the challenges they face.

Character development is a standout feature of Island of Glass. Each guardian brings their unique strengths and weaknesses to the table, and Roberts skillfully explores their individual arcs. The camaraderie among the guardians is palpable, and their interactions are filled with humor, loyalty, and a sense of shared purpose.

The evolution of Doyle and Riley's relationship is particularly well-crafted; their initial attraction blossoms into a deep, abiding love that is both passionate and grounded in mutual respect.

Roberts' writing style is engaging and accessible, with a fluid narrative that keeps readers invested in the story. The pacing is well-balanced, allowing for moments of tension and action to be interspersed with quieter, introspective scenes that deepen character relationships.
