Winter is dying, and spring is bringing the land back to life.

In the weeks that followed the successful campaign to eliminate the stalker menace, David and the ladies have returned to Haven. It's been a peaceful four weeks, a return to as close to "normal" as you can get in a post-apocalyptic world where undead monsters roam the landscape and humans live alongside a half-dozen different species of inhumans.

But a new threat has been brewing the whole time, looming on the horizon like dark clouds before a brutal storm: the vipers. The water-bound monsters have been boiling up out of the lake not far from Haven all winter, more than there should be, attacking places where normally they wouldn't be found. And it's only getting worse.

Lara, the badass military babe from Lima Company, shows up with another proposition: Her group wants to pair with the warriors of Haven once again to deal with the growing threat of the vipers. David immediately agrees, and they set to work on figuring out how to handle this situation. Unfortunately, it's not going to be as straightforward as last time. They're going to need the help of an expert, and the only expert they can find is Azure, one of the inhumans known as the squids, who live in the lake and keep to themselves. And just like last time, it's going to take everything to get through this alive....

Haven features, badass women, settlement building, and lots of monster fighting.
