While enjoying a day with her mom, Harley stumbles across a comic book of her adventures. Taking the time to read it is one of the worst things she could do, for when the comic catches up to the moment where they are (the comic shows Harley and her mom reading the comic), both Mom and reality begins to unravel! Harley is destroying DC Continuity and this summons Jonni DC, Continuity Cop! (This is a crazy DC character that has existed for quite a long time, and is only really brought out when the writers are allowed to do really crazy stuff...)
The shock waves echoing through the universe allow for some really crazy stuff, but eventually Harley is able to stop it (mostly), and brings her mom back into existence by drawing her back in. (Just read it. You'll understand.) All is not well though, as she has brought Golden Age hero Captain Triumph in to the Modern Age! This hero is used to fighting Fascism and has a hard time adjusting to today's world. Harley, continuing her typical comedy, is able (with Jonni DC's help) to get Triumph back to his time.
The third section of the Volume deals with a new minor villain: Minor Disaster! Her father, Major Disaster, is a long-standing DC villain who uses a Disaster Dial to cause all kinds of chaos: earthquakes, fire, tornados, etc. Minor Disaster's dial causes things like a text from your ex while you are on a date, a fart in public, or getting a soggy sandwich. (A concept this hilarious and weird would only work in a Harley Quinn title...) Minor Disaster sees that Harley is getting popular on Youtube (or DC's equivalent) and decides that if she can take down Harley, maybe she'll finally get some respect from her father. Most of the tactics don't work until the Dial starts doing major disasters, and even though Harley defeats her, we are left with a Volcano in the water just off Coney Island. (It will be really funny to see if this comes up again, either here or in another DC title.)
What's next for DC's Queen of Comedy? Can't wait to see where it goes next, and I am happy that Connor and Palmiotti's absence from the title has not caused it to fail.
Strong recommend. (I'd be surprised if Harley ever had a bad Volume...)
