It seems the most part of suggestions here concern superheroes comics.
So I would like to suggest more about graphic novels
if you don't mind.
I am not sure if this genre is as popular as in France or Italy. But I would like to present few of these titles. Graphic novel is called Bande Dessinée (BD) which litteraly means "Draw Strip".
As you know (or not), french-belgian comics are very famous in these countries but are very rare overseas. Few of them are translated in english.
First, there is a partnership between the french publisher Soleil (essentially a fantasy publisher) and Marvel for few years now.
So Marvel bought the copyright of few series :
- Universal War One
by David Bajram : a space opera serie in six issues. It's about temporal travel. I highly recommand it. The story is quiet awesome.
- Sky Doll
: an italian serie in 3 issues. Very beautiful drawings. Story is all right. SciFi story again. But not as awesome as UW1.
Marvel published few other titles of Soleil : Scourge of the Gods, Samurai, Ythaq.
Okay now the following titles can be bound in english BUT not sure if it's available on USA territory.
(Sillage) by Jean-David Morvan and Philippe Buchet : a really popular SF serie in France. There was a controversy about the first issue : as you know american publisher are very careful about nudity. Navee is topless during all the first issue and the US publisher censored it with an ugly black mark on her tits T_T
US Censorship:Requiem, Vampire Knight
by Pat Mills (who is know in US I think) and Oliver Ledroit (this guy is a great artist). An original fantastic story about vampire. Recommanded.
To finish my selection, I will recommand a very good american graphic novel by Craig Thompson : Blankets
which a very beautiful love and autobiographic story. Read it, it's an order ^^
If you want more informations about foreign comics translated in english, I can recommand this website : http://koti.mbnet.fi/~z14/euro-comics/index.html
