The Ice Queen - Petra Larson series book 1

Petra Larson is a head turner; people notice her more than other women. Young, smart and confident, she is an example of a beautiful, successful woman who appears to have it all, but there is more to her than meets the eye: her job at a lettings agency cloaks a dangerous and lucrative secret life.  Jerry Byrne meanwhile is a normal guy working in a normal job, preferring a quiet, normal life. When Petra is brutally raped, there's only one person she can turn to - her boss, Jerry Byrne. Following attacks on other women and when a fatal accident takes place in suspicious circumstances, something must be done to end the violence and it is only when Jerry's life is set on a collision course with Petra's that he discovers what she is capable of.
Forced to react, one way or the other, how will the normally indecisive Jerry respond? Will he support her actions? Can he remain within the law? Will this mean the end for them?
