Book Four of the McCall Initiative series, Liberation continues to raise the ante when Logan and Piper plan to spring President Jefferson Cooper from his enemies' prison. Well written, with "real" character that you feel you know personally, and care about as much as your family. It's been said that Nowak is "so mean to her characters', as she throws more seemingly insurmountable obstacles at them, but at the same time she gives them the strength, intelligence and cred to win. Highly recommended. This is a serial so start with Episode 1.1. You'll be hooked from word one.
