Wildblood Series Book 1 by S. A. Hoag
Problem is – there’s something dangerous out there, just beyond The Vista, watching them.
As Vista Security, they are sworn to protect; as Security Command, Team Three may be forced to break those oaths to save everything they’ve ever known.
The Vista: Book 1 of The Wildblood series takes place in the near-future where the Earth has been mostly emptied of human beings by a short and devastating world war. Venturing beyond the safety of their valley may be the best move Security has ever made; it’s absolutely the most dangerous.
