Code Murder - Paperback

Feisty sixty-year-old twins Dix and Lil Ruiz share a house, but little else. Dix, a psychology professor and martial arts student, sees life through a positive filter. Lil, an accountant and general misanthrope, reacts to life's spitballs by blowing the top off the Armageddon chart. When Dix witnesses the murder of a software-coding guru known for exposing cyber-crime, she is determined to find the killers. Suddenly catapulted into a feud between a crew of cold-blooded cybercriminals and a mob boss, the twins must fight for their lives. But how can they survive when both sides want them dead?
