JOHN CONSTANTINE: HELLBLAZER
A black label book which features John Constantine set in a vertigo universe. The book sadly got cancel at issue 12, but if the sale of the graphic novel / trades for this series is selling high, this will give DC some attention to let Simon development a second series of this Helllblazer.

STRANGE ADVENTURES
One of the best selling worth adventure with Adam Strange. The storytelling and visual art are magnificent and intense short but great art. If you have not purchase any issue of Strange Adventure, please check out soon in your own LCS.

SUPERSONS
One of the best DC series to come out and is suitable for all ages including the kids. They can get to learn more about these Superheroes's kids. Moreover, the upcoming " Challenge of the Super-sons" series will be publish on April. So mark on the calender and don't miss out to order them.
These are so far the best books I could recommended but there is more. This could show DC that fans want more variation from comics.
