i came across this story tonight and i just had to finish it! i'm loving it! the mesh of the worlds is fascinating and the text manages to give u a taste of urgency and despair and loss and harried battles. great writing. and the spin of the apocalypse and the mesh of the two universes works and balances out and i can't wait for the next chapter!
ps ahem, i suspect the i found the book on a store and just thought i try and see if it worked approach won't work now; what with an angel they know by name face planting onto the furniture...
