Erica Henderson is ending her run on Marvel's acclaimed The Unbeatable Squirrel Girl series.Making it "officially official" on Twitter, Henderson said the issue she's working on now will be her last in the series. She said she's leaving the book to focus on her creator-owned work, but made clear that The Unbeatable Squirrel Girl will continue, despite her exit. She'll also still be doing cover art for the series.

This wraps up three years of Henderson's work with the series, one that has been highly-regarded by critics and fans alike, including an Eisner Award for "Best Publication for Teens (ages 13-17)" in 2017. It even spawned an original graphic novel in The Unbeatable Squirrel Girl Beats Up the Marvel Universe. Henderson also did a stint on Archies Comics' popular Jughead series.

The team of writer Ryan North and Henderson persevered through rumors of cancellation and line-shattering events like Secret Wars, but the series always remained smart, diverse and incredibly funny, making it one of the go-to books for on-boarding new comics readers.

Henderson said she'll miss working with Marvel characters and her creative team on the book but is looking forward to the future. Her new project has not yet been announced.
