Unity: A Post-Apocalyptic Zombie Survival Thriller Series (Green Fields Book 6)

United we stand, divided we fall

Once again reunited, the Lucky Thirteen set out to hunt down their adversaries—only to be met with an entirely new set of unexpected obstacles. As much as Bree is burning to finally get her revenge, it soon becomes obvious that on their own they are no match for the forces opposing them. With giving up not an option, they will have to find a way to bolster their numbers—or failing that, make the ultimate sacrifice.
