I'm currently reading the Locke and Key series by Joe Hill and Gabriel Rodriguez: http://en.wikipedia.org/wiki/Locke_%26_Key
I'm reading the collected editions:
1. Welcome to Lovecraft
2. Head Games
3. Crown of Shadows
4. Keys to the Kingdom
5. Clockworks (not yet released)
I'm really impressed by the quality of the whole package. The writing and storyline is excellent, the artwork and colouring is amazing and the quality of the books themselves is absolutely top notch.
If you're looking for something different that is without doubt a top quality graphic novel then I can't recommend these highly enough.
