Wolf Trap

Sullivan's second Brian Rhome thriller follows his debut Sleeping Bear with a bigger, more geographically sprawling plot, and reviewers noted the same strengths and strains that tend to define the genre at speed: propulsive pacing and evident research into military and intelligence tradecraft, set against a large cast that occasionally blurs together under the weight of its own plotting. Critics placed Sullivan in company with writers like C.J. Box and Brad Thor, praising his willingness to keep multiple storylines moving without letting the book collapse into confusion.
