Event books are blockbuster storylines that typically span multiple titles at once, either company wife of 'family wide' such as all Avengers or Batman titles. Event books either have their multiple parts spread over multiple titles or have a main limited series with various tie-ins. Below I've listed various event books by title with published in parentheses that are available in the catalog and supplemented by titles available through Hoopla Digital, which you can also access with your library card.
