Her Fearful Symmetry-Audrey Niffenegger

Seriously, I can never get this author's last name right! Sheez... Loved Niffenegger's writing to death. As usual, her book starts off a little stale but as the story progresses, you just can't put the book down. I admire her for the novelty and obscurity she brings into her stories. Stories, that you can never imagine or expect. This is a strange story of Elspeth and Edie, twin sisters and Edie's daughters, Julia and Valentina, who were twins too. Elspeth died of leukemia right at the beginning of the story, leaving her lover, Robert, behind.
What happened after is, depending on your beliefs are, incredulous. Elspeth became a spirit, lingering behind in her old apartment, unable to leave. Came Julia and Valentina, one vivacious, loud, and bossy, the other timid and mousy, to take over Elspeth's apartment.

Robert and Valentina, fell in love, shortly after, and despite their age difference. Julia, of course, felt jealous, to have Valentina "leave" her for Robert, the ghost of Elspeth felt the same and started getting ideas, when she realised she has the power to take another's soul away.

The story is strange but hauntingly beautiful. It makes you sad, makes you gape in incredulousness... leaves me despising Elspeth, feeling sad for Valentina and Julia, and then applauding what happens to Elspeth at the end of the story.
