What happens when you hit rock bottom and discover that you didn't bounce back up to the surface?

Kevin Dubois knows. Monotony and loneliness have become his constant companions, and he's drowning. But he's not the only one. Stefan Smith and Tara Zlatari never meant to swim in such deep waters at all, but months of tension have slowly dragged them down to a point where the light cannot reach.

Lillian and Gabriel McGonaghall thought they had reached calm waters, but here the undertow is tricky, and they find themselves throwing ropes to their friends and family, trying to pull everyone up while steering around unseen dangers. But they must stay the course and stick together, because immortal or not, sometimes it is impossible to find the surface alone.
