Fortress

"Incredible twist! I was completely blown away by the big reveal, which makes perfect sense given the clues sprinkled throughout the series-but still hits you like an unexpected gut punch!"
What caused the EMP? Why is the government rounding up civilians?
All answers are revealed in FORTRESS, the stunning finale to the heart-pounding RECKONING books.
Joe and Meg Birch continue their perilous journey through a hostile and occupied city to seek shelter in a local university. As they settle into their new life among friends and fellow survivors within the university's hidden tunnel system, the U.S. military continues its relentless seizure of seemingly innocent civilians. After a student is openly murdered by soldiers, the Birch's and their close group of friends decide to take their chances on the outside. They make their way to a nearby survivalist camp, where Joe's brother has presumably hidden to ride out the disaster. However, they quickly discover that the survivalist camp is anything but safe, and that nothing is what it seems in the aftermath of the RECKONING.
