Sundown

The busy final entry in Warren’s Sky King Ranch trilogy (after Sunburst) follows a doctor and former special operative as they work to prevent a biological attack. Colt Kingston, a former Delta Force soldier, doubts infectious disease expert Tae Price’s incredible account of surviving abduction by the Russian mafia after the plane they were in crashed in the Alaskan wilderness close to Sky King Ranch, where Colt lives with his two brothers. Colt starts to trust her after they trek to the wreckage, where Tae reveals that she had been working on a vaccine for a rare but lethal strain of smallpox that may have been weaponized by the Russian mafia. Tae’s work put a target on her back, and when Colt and Tae return to the ranch they find it under siege by Russian thugs. Special operatives step in to end the attack and help Tae set up a lab in Florida where she must finish the vaccine and learn to trust God while the Kingston brothers race to stop a viral attack on Disney World. This picks up many threads from previous entries, and while series fans will enjoy the satisfying payoffs, they add up to an overstuffed conclusion that strains under the weight of its many moving parts. Readers will enjoy the action, though they may get lost in the din. (Nov.)
