For all that it does sprawl a little, this is actually a surprisingly tight crossover. Few parts of it don’t align well, and the parallel storytelling – especially in week four – is inspired. A shame so few of the tie-ins are reprinted. It fits into the main timeline here.

- Continues directly from the previous two issues of Wonder Woman.
- These issues of Swamp Thing reference events from Millennium, but are not bannered as crossovers.
- These issues of Young All-Stars are placed here as they follow on from Secret Origins #22.
- These four issues weave in and out of each other telling intersecting stories, and can be read in any order.
- Justice League International #10 and Firestorm #67 occur in parallel.
- Only the Woodrue story from this issue is reprinted here.
- These two issues of Legion of Super-Heroes came out in weeks 2 and 6 of the event respectively, but take place a thousand years later, and have no real bearing on the rest of the event.
- A new series that spins out of the events of Millennium and Suicide Squad.
- A new series that spins out of the events of Millennium.
