Girls with Slingshots: Volume Four | Danielle Corsetto
Aka. "The Wedding Issue." This book introduces Erin, and features Maureen and Jameson's wedding. R. Milholland's "Something Positive" crossover strips are printed in the back for easy reference, and as always there's a "How to Draw" section, featuring Candy and Thea. Chock full of sketches, plus fan art by other creators!
