Doomsday Game (The Apocalypse #3)

The Conclusion to the alternate worlds saga.

It's the end of the world... again.

Over the years, the Pathfinders - distinguished by the fact of their each being the sole survivor of the apocalypse on different parallel Earths - have become a tight-knit team, exploring alternate Earths in the hopes of finding one to which they, and the Authority, might one day evacuate.

Now one has been an untrammeled Eden on which humanity never evolved. 
But just when their job seems over, three new threats one is an old, if unexpected, enemy; another comes from within the Authority itself; while a third is so completely unexpected that the Pathfinders are quickly overwhelmed.

Can Jerry, Rozalia, Nadia, Yuichi, and the others face up to this final threat - or has their luck finally run out?
