I skipped the last book I had for The Remaining after I got maybe 4 hours in. It was a prologue to the main story and I just didn't really care for the american army man crap.
So went back to do some Outlanders for a bit before trying out the Lee Harden series of books (which is more "The Remaining").
Outlanders is good although it is getting a bit wild with many different dimensions going on at the moment.
