Books like Eternals

The first time I read this I was a diehard Gaiman fangirl and I gave it 4 stars.This time around?Eh. It wasn't bad, but it wasn't exactly satisfying (to me) in any sort of a meaty story sort of way. It does, however, have that typical Gaiman smell to it. So, if he can do no wrong in your book, then you'll want to check this out. The Eternals are these super-powerful & immortal beings that were created before humanity, and they (I guess) act as our protectors when even bigger, more powerful, older immortal beings decide it may be time to end us. Ish. Due to vaguely explained happenings, the lion's share of these Eternals have been mindwiped and have no idea who or what they are anymore. They're living among us as humans and occasionally superheroes. The story takes place during the events of the Superhero Registration Act, so there are a few cameos with Tony & Co. that gives this a somewhat Marvel universe-y feel to it. But not really.At the end of this I was kind of left scratching my head, but maybe this isn't the whole thing?Is there more to their story? Preferably told by someone other than Neil Gaiman? Anyone?
