Seconding the Sandman by Neil Gaiman Also - The Dark Tower series by Stephen King The Walking Dead Hellboy V for Vendetta Humanoids by moebius - if he leans towards the art side of things, and you want a gift that is a collectable.
I read The Arab of The Future parts 1 & 2 this year and really enjoyed it. It’s another memoir of a chap raised in France who then is taken by his parents to live in first in Libya and then Syria. Loved the art and there is some lovely humour which is just as well as his child hood is all manner of wtfery. His dad is a total crazer.
