While many of us spent Monday barbecuing, watching X-Men: Days of Future Past or otherwise enjoying the day off from work, comiXology got a jump on the season with the launch of its "Summer Reading List," offering one free digital comic a day for 20 days.

The initiative debuted with Detective Comics #827, by Scott Snyder, Jock and Francesco Francavilla, the issue that began the writer's celebrated run on Batman. What's today's selection? It's a good question, one that should be answered any ... second ... now.

It's worth noting that customers can also gift each day's selection to others, for free. “ComiXology fans deserve an amazing line-up of outstanding comics to discover from top publishers so they can read and share with everyone they know,” Chip Mosher, comiXology's vice president of communications and marketing, said in a statement. “We know nothing beats a sunny day reading comics, except twenty days and free to boot! By the end of the promotion comics fans will have a great summer reading list.”ComiXology's "Summer Reading List" continues through June 14.
