Editor's Review ★★★★☆

AudioBook Atlas

I devoured Sleeper Agent: Nemesis in a single, thrilling sitting – a testament to the audiobook's unrelenting pace and Rupert Degas's captivating narration. Degas brings a nuanced, layered performance to Cooper Fox, conveying the character's emotional depth and inner turmoil. The production quality is top-notch, with crisp sound design and seamless editing. If I have any quibbles, it's that some of the supporting characters feel a tad underdeveloped, and the pacing can be frenantic to the point of occasional disorientation. Still, these are minor complaints in an otherwise electrifying listen that will keep you on the edge of your seat.
