Supernatural mystery

A very different YA book from the 90s. A teen girl discovers a dead girl's diary that contains experiences that soon come to feel like her own. Like she was once this girl. . .

I don't buy into the whole reincarnation thing, so I wouldn't endorse that aspect of the premise. But the way Smith executes the mystery is interesting, and in many ways its themes resonate more maturely than other YA mysteries.

The transition of Delia to the dead girl is so smooth and effective that you hardly notice it's happening, sort of like the transition you see with Cady in Mean Girls.

The writing style was a bit rough around the edges, but entertaining for the most part. It's strange that you can't find anything about this author. . .

But the ending, well, two things: 1) Way too sudden, like the writing starts to propel you toward something and then cuts off. 2) Totally shocking.
