This was a series of stories I read not long ago, but being an old fart, have already forgotten. Original story was about a security expert (had contacts and worked for various government on a contract bases). I THINK caught his wife cheating and gets some revenge and divorces her.
meets and marries another,she has has sisters who become mc's in other stories. I remember that a daughter becomes a master hacker and does some jobs for another guy in the security field, saves him, and marries him.
a little help please
