Dian has lived many lives. But she cannot remember them all.
She has lived them alongside Lusifer, Storm and Sus, who deliberately keep her from remembering them.
They are her friends, and lovers, and they need her to keep collecting and saying the formulas that will fix the world. The distraction of a memory could be the difference between heaven and hell.
Only when they have all been said can everything be at peace once more.
But the forces of evil are against them, and time may be eternal, but it is not on their side.
