Deadly Innocence on Karla Homolka & Paul Bernardo - the "Ken and Barbie" killers.

There are 2 other big books on them, but I haven't read either.

There are a few books that explain the crimes in detail - using transcripts from the videos shown in court (the tapes of the actual crimes - the same ones that were ordered to be destroyed). You can buy the books in Canada, I own them. They're some of the most disturbing true crime books I have ever read - I'll never get that stuff out of my mind, the things they did to those girls. They're are really interesting, though.

Here are the links for the books, the first books has the most information (almost transcripts from) the video tapes:
