Three blades Life, death, what's in-between

There are seven pulled into this fate. 2,3,2 that's how it goes for each blade.
2, Rook and Therion are as different as night and day, One quiet and closed in the other cheerful and bright, death has followed them time and again, they know not what they hope for. Death's blade will give them anger, will they have the strength to choose sorrow instead?
3, Anna, Izzy, and Werner. An artist, a reader, and an inventor. Some might find connections in their crafts, to them they understand how to drift off away, they have few anchors. When they get the in-between's blade will they have the courage to face reality and not turn away?
2, Addie and Iska, a pair of red haired twins, one can be gentle the other rather protective. They care about each other and at times you can't tell the difference between the two. Yet difference there is for we all aren't the same. When they face life's blade will they be brave?
The ghosts are coming. Some vengeful, few helpful, other simply don't care.
Three vengeful spirits with power centuries old, three blades past through the ages, and seven teenagers trying to win this race.
They have to win to save what they lost. Thats all for now, don't want to mess up the fun part.
