Heart's Prisoner

A military behaviorist finds herself in uncharted territory when she's assigned to study a captured alien warrior in Olivia Riley's science fiction romance. Set inside a high-security base, the story pits Lana's professional instincts against a deepening fascination with her subject, a powerful and enigmatic being known only as Xerus. The tension between duty and desire forms the core of this first entry in the Dark World Mates series, as both captor and captive navigate a charged dynamic where neither can fully trust the other's motives.

Maxine Mitchell brings a steady, grounded presence to the narration, anchoring the story's more intense moments with a measured delivery that keeps the emotional stakes credible. Her pacing suits the slow-burn nature of the plot, letting suspense and attraction build naturally across the runtime. At just over ten hours, the audio format rewards listeners who appreciate character-driven tension, and Mitchell's voice work gives both leads distinct personalities that hold up through the novel's darker, more heated sequences.
