Tomorrow is Free Comic Book Day (see the list of free comics for more details). In honor of that, I thought I'd give some recommendations for other comics to check out at your friendly neighborhood comic book store. (Don't know where that is? Check out the FCBD Store Locator). I tailored my list to people who don't normally read comics and limited myself to ten to (I hope) avoid going too long.
By the way, if you're buying for kids, the first two below are all-ages books, Astonishing X-Men is rated Marvel's equivalent of PG-13, and Maus is great for anyone old enough to understand and handle a book about the Holocaust; the rest are mature readers titles (about the equivalent of an R rating).
Ongoing series:
The Spirit - A fun detective series with standalone issues - even though the latest issue is something like #17, you don't have to read the other 16 to know what's going on.
Runaways - A group of teens with superpowers finds out their parents are some of the world's worst supervillians. Early issues are written by Brian K. Vaughan (see Ex Machina); now written by Joss Whedon, creator of Buffy the Vampire Slayer and Firefly/Serenity.
Astonishing X-Men - In my opinion, the best X-Men series since the Claremont and Byrne days of the '80s and one of the best superhero series published today. Like Runaways, it's written by Joss Whedon.
Ex Machina - Think The West Wing, but instead of focusing on a president, it's about the mayor of New York City, who just happens to be his world's only superhero - a superhero who saved the day on 9/11. Written by Brian K. Vaughan, who is not only my favorite current comic book writer, but also a writer and producer on the TV show Lost.
Fables and its spin-off Jack of Fables - Fairy tale characters like Snow White, Jack ("and the Beanstalk," "Frost," "Horner," and many more all in one), etc. living in secrecy in the modern-day real world as refugees from their homelands, which have mostly been taken over by a dictator known as the Adversary.
If you're worried about jumping into the middle of a series, all of the above have trade paperback collections of back issues. You can also check out the books below.
Completed Series, Limited Series, and Graphic Novels:
Watchmen - The only graphic novel to win a Hugo and the only one to appear on Time's list of the best modern English-language novels, Watchmen is about retired (and very human) superheroes in an alternate-history Cold War U.S. The former superheroes try to figure out what's going on when one of their own is murdered, while conspiracies and the threat of nuclear war are constantly hanging over them. By Alan Moore and Dave Gibbons. One volume.
The Sandman - The only comic book series to win a World Fantasy Award and the only one to appear on the New York Times Best Seller List, Sandman is about Morpheus/Dream/The Sandman, the personification of dreams. He travels (literally) to Hell and back, meets William Shakespeare, and has run-ins with his siblings, The Endless, each of whom is also the personification of an abstract concept (Death, Destiny, etc.). By Neil Gaiman and various artists. 11 volumes.
Maus - The only graphic novel to ever win a Pulitzer Prize, Maus is the true story of the writer/artist Art Spiegelman's father Vladek's experiences as a Polish Jew during the Holocaust. It also depicts the relationship between Art and his father as Art gathers material for the book. By Art Spiegelman. 2 volumes.
Y: the Last Man - A plague has killed every male mammal except Yorrick Brown and his pet monkey Ampersand. Besides the drama and suspense of dealing with the collapse of society and Yorrick trying to find his fiancée Beth while avoiding capture (or worse) by various factions, the series also has a lot of humor. By Brian K. Vaughan & Pia Guerra. 10 vols.
I'm not sure if I completely did justice to all of the above, but I think I got the gist of them. You can find out more with a little searching online; Wikipedia's usually a decent starting point.
Enjoy!
