Conner is back from his adventure saving the life of the President's daughter. On his next missiong, he will be protecting twin daughters of a wealthy businessman on their yachting vacation. Conner will not only have to deal with sea pirates, but also the girls' future stepmother, and the rebellious nature of one of the twins.
The books in the Bodyguard series have actually been split into two volumes each, so even though Hijack is the third book in the series, it is really just the first half of the second book. Even though Conner survived his first assignment, he is still very unsure of himself even though his trainers continue to praise him for his progress. Also, some of Conner's fellow trainees are a part of the story; Ling goes with him on the mission, but resents that she isn't in charge, Amir shows his disappointment because he still hasn't gone on a field mission yet, and Charlie continues to display more than a collegial concern for Conner. Overall this is another good installment in the series
