Collateral Damage by Lindsay McKenna

Ex-SEAL Cal Sinclaire is going to marry Sky Lambert, and everything seems to be a dream come true for them until a shocking event occurs. Sky disappears on the day before her wedding. Anguished, Cal calls on his old SEAL team friends, together with a Master Chief at the SEAL units, to try to find Sky. No one has any idea who did it or why. They have no evidence to go on to locate her. She could be anywhere in the world, and his SEAL team dives into finding microscopic clues to her possible whereabouts. Come hell or high water, they will find her…or else.
Sky’s whole world implodes as she slowly regains consciousness and finds herself bound, gagged and blindfolded after being heavily drugged. She has no idea who has done this to her, where she is or where they are taking her. Her heart cries out for Cal, for all they’ve gone through over the years, and for finally being able to admit their binding love to one another. WHO has done this to her? All the years in Witness Protection, hiding at the ends of the Earth from a crazed Russian man who wanted her for his own, whether she wanted to be his or not. She was rid of him, killed earlier in the Peruvian jungle. Her dreams are destroyed, and Sky sees no way out–not realizing she is collateral damage.
