Helena Newbury's No Angel is a gripping romantic thriller that deftly combines elements of suspense, romance, and personal redemption. The novel's premise is intriguing from the outset: a doctor falling for her patient, who happens to be a notorious federal prisoner. This setup immediately promises a complex narrative filled with tension, moral dilemmas, and emotional depth.

The protagonist, a doctor whose name is not revealed in the blurb, is portrayed as a "geeky" yet compassionate professional who finds herself drawn to Gabriel, a former Marine turned prisoner. The dynamic between these two characters is the heart of the novel, and Newbury does an excellent job of exploring their evolving relationship. The doctor’s initial attraction to Gabriel is fraught with internal conflict, as she grapples with the ethical implications of her feelings. This internal struggle is portrayed with sensitivity and realism, making her a relatable and multi-dimensional character.

Gabriel, on the other hand, is a fascinating character study. He is introduced as a "growly, cocky bad boy," but as the story unfolds, layers of his personality are peeled back to reveal a man who is much more than his criminal past. His background as a former Marine adds depth to his character, providing a glimpse into the hero he once was. This duality in Gabriel's character—between his past heroism and present notoriety—creates a compelling tension that drives the narrative forward.

The theme of redemption is central to No Angel. Gabriel's promise to do something good with his life after the doctor saves him is a pivotal moment in the story. It sets the stage for his transformation and underscores the novel's exploration of whether people can truly change. This theme is handled with nuance, avoiding the clichéd notion of a "bad boy turned good" and instead presenting a more realistic portrayal of personal growth and redemption.

Newbury's writing shines in the novel's action sequences, particularly during the latter half when the doctor is captured by a cartel. The tension is palpable as Gabriel races against time to fulfill his promise and rescue her. The wilderness setting adds an additional layer of danger and intimacy, forcing the characters to rely on each other in ways they hadn't before. This part of the novel is where the romance truly blossoms, as the isolation and shared peril strip away their defenses and bring their feelings to the forefront.

The novel's pacing is well-executed, with a balance of introspective moments and high-stakes action. Newbury's ability to maintain suspense while developing a believable romance is commendable. The chemistry between the doctor and Gabriel is electric, and their interactions are charged with both tension and tenderness. The author skillfully navigates the fine line between romance and thriller, ensuring that neither element overshadows the other.

One of the most compelling aspects of No Angel is its exploration of trust and sacrifice. Gabriel's secret, which threatens to tear them apart, adds an additional layer of complexity to their relationship. This secret is not just a plot device but a crucial element that tests the characters' trust in one another. The resolution of this conflict is both satisfying and thought-provoking, prompting readers to consider the lengths one might go to for love and redemption.

In comparison to other romantic thrillers, No Angel stands out for its character-driven narrative and emotional depth. While it shares similarities with novels like The Witness by Nora Roberts or Mr. Perfect by Linda Howard, Newbury's work distinguishes itself through its focus on personal transformation and the moral complexities of its characters. The novel's blend of romance and suspense is reminiscent of the works of Sandra Brown, yet Newbury's unique voice and perspective make No Angel a fresh and engaging read.

Overall, No Angel is a compelling novel that will appeal to fans of romantic thrillers and character-driven stories. Helena Newbury has crafted a tale that is both thrilling and emotionally resonant, with characters that linger in the reader's mind long after the final page. The novel's exploration of love, trust, and redemption is both poignant and inspiring, making it a standout addition to the genre.
