Apocalypse memories - Laura J. Burns

Willow can feel something strange happening, but seems as if no-one else has even noticed. They have problems of their own to deal with. Personal issues... relationship issues... the usual, everyday hassles that life is all about. But Willow's fears are on a whole new level. She is still not happy with using her powers again, not after what happened when she lost control. People died. The power within her is massive, and if something should turn it to darkness, nobody is safe. Who knows what she might do?
But her instincts are right. A wolf in sheep's clothing has set off a series of freakish events: rivers of blood, flash storms, and the arrival of an unbelievable supernatural being. The apocalypse is here. Again. And while the world falls to pieces around them, Buffy and her friends -- including Giles, returned from England -- must decide what is most important. There is one last hope: a secret long-lost spell. But its side effects are dangerous. Is Willow ready and willing to take the risk...?
