Most of the issue is concerned with Dinah starting a career as a solo musician, ignoring the pleas of the superhero community in joining their battle against something called Ravedeath. She finds time in the middle of all this to meet and marry Oliver Queen (whom we are told died in space in the most forced reference to David Bowie's Space Oddity ever) and gave birth to a daughter who might be Ditto - the time-manipulating McGuffin child.
Oh, and it turns out Dinah's mother taught her some secret reality-breaking punch when she was a baby, but she doesn't remember it until she's on her deathbed, where her lifelong study of music and chords allow her to understand how to use said technique to undo what her mom did and beat-up an 1980s rock-and-roll vampire demon thingy.
Maybe I need to be on a higher quality of medication for any of this to make sense?
Personally, I'd much rather see the Justice League fighting some evil alien invaders than watching Dinah Lance sit around a studio and conducting interviews about her upcoming album. But whatever. At the end of the issue, Dinah abandons her singing career, trades her thigh boots for army boots and goes off into the world freed from the baggage of her previous life. Her husband is dead. Ditto has magically been erased from the memories of everyone but her. And Amanda Waller seems content to leave her be... for now.
Annie Wu returns to do some of the artwork for this issue but even she can't disguise what a convoluted train-wreck this book became as Sandy Jarrell continues to apply the minimum amount of effort in everything. Lee Loughridge, at least, continues to color everything expertly but even a prettily-painted turd is still a turd.
And so Black Canary ends - not with a bang but a whimper. It was a tale told by a idiot, full of sound and fury, signifying nothing.Thankfully, based on what we've seen of Green Arrow and Batgirl and The Birds of Prey, Dinah is in much more capable hands now.
