Right then. We get a lot of people asking us what order they should read the shows in, what happens when and that kind of thing, so we thought it was time to organise an official timeline for you, so any newcomers know where to start!
We'll start with the televised Buffy and Angel shows and lead into the MZP series from there. All shows listed on the same line take place around the same time (or 'year,' if you like), and then on each line it's the first show which is the earliest, and so on.
