Veils, Book 3. The Veils Trilogy, #3

Now married, Griffin and Nat couldn't be happier to have shared the moment with their friends, but the honeymoon period won't last long. Still plagued with the veils and acid rains, they're just trying to do what they do best-survive. However, things seem to be changing, improving. Cars are working again, guns are firing, there's even electricity, but still they find themselves traveling through time.
With each event, it seems they're getting closer to their original eras. The world looks to be healing itself, and as long as they stick together, they believe they'll make it through. The only problem is, if their theories are correct, at some point they will have to let each other go to return to their own year where it all began. Hope prevails, but uncertainty continues to rear its ugly head. Will it ever be over? And if it does end, will they be able to reunite with their future selves?
