webcomic, and here the entire saga is collected in one volume. The story follows a young woman named Mary Posa, who is physically quite strong and works in the Butterfly Gang run by supervillain Monsieur Butterfly.
This comic was created by Kristen Gudsnuk, who uses a very cartoonish style that is charming but energetic. She also crams her backgrounds with lots of gags and details that highlight the story and add a touch of glee. She speaks about her work on Henchgirl in this interview.
The reviews I have read of this volume have been positive. Dustin Cabeal wrote that "not only is this one of the best superhero comics I’ve read in many
years, but it’s one of the best comic books I’ve ever read, period." Publishers Weekly was more measured, stating that the opening chapters "of Henchgirl, drawn in a charming style somewhere between Scott Pilgrim
and Steven Universe, have a delightful and spontaneous energy, but as
the series progresses, Gudsnuk begins stitching her ideas into a
narrative and things slow down a bit from the sparkling opening." Travis Pelkie summed up, "So if you’re looking for a book set in a superhero world where the real story is how a young woman finds her place in life, try Henchgirl."
Henchgirl was published by Dark Horse, and they have a preview and more info about it here.
