It's up to Val to unite the lost twins, and she has no clue how to do it. Along the way, Valkyrie learns some VERY dark secrets about her skeletal friend's past, and tries to sort out her mess of a conscience and love-life. And on top of that she's gotta get Tanith and Ghastly together. Oh yeah, and soon Delilah is going to start the biggest war the world has ever seen.
