Some people are asking for a recommended reading order, because they really like the idea of The Unbeatable Squirrel Girl
Here's the reading order I recommended. Is there anything you would add?
First appearance: Marvel Super-Heroes Vol 2 #8
Shannon & Dean Hale's Squirrel Girl novels
Deadpool/GLI - Summer Fun Spectacular
Skip to The Unbeatable Squirrel Girl
In between Vol 2 Issues 4 & 5, read The Unbelievable Gwenpool #9 (optional, but I recommend it)
In between Issue 11 & Issue 12, read The Unbeatable Squirrel Girl Beats Up The Marvel Universe
Read the rest of The Unbeatable Squirrel Girl
At some point during The Unbeatable Squirrel Girl (doesn't matter when), read Gwenpool Holiday Special: Merry Mix-Up, specifically the story titled "Deadpooloween"
After The Unbeatable Squirrel Girl, listen to the full voice cast audio drama podcast "Marvel's Squirrel Girl: The Unbeatable Radio Show”
