You thought Farnhams Freehold was better?
Their preps were a cave, a cow, and a case of canned milk.
The story as a whole = a better read.
“Pulling Through” by Dean Ing ( ISBN-10: 0441690505
ISBN-13: 978-0441690503 )would be better, tho focused on a nuke exchange - had far more and better tips. And a story. The follow-on is a series called the “Rackham FIles”. Just to note Dean is an angineer.
