BODYGUARD LOCKDOWN (4) by Donna Young: Former black ops agent Booker McKnight is intent on revenge against the arms dealer who killed his wife and the men in his unit — and Dr. Sandra Haddad is his only way to bait the trap. Five years before, Sandra was working on a rapid healing serum when it was subverted and used in the deaths. Sandra testified in the trial of the man who did it, but he escaped and is now intent on getting his own revenge against the doctor who betrayed him. The question is, can Booker protect Sandra from the very man he is trying to trap? Set in the heat of the desert, Young’s twisted, cold-blooded plot blurs the lines between good and evil at a breakneck pace.
