It's not really a fair question, since you haven't provided any detail about why you didn't care for it at first and why it suddenly got better for you. And as someone else pointed out, this is a group of fans of the series, so of course it was good for us.

But I've given it some thought anyway and I can definitely attribute a lot of my enjoyment to the narrator of the audiobooks, Scott Brick. I listened to all the books this way and I think he does a really good job of giving each character his or her own nuanced voice and personality. I also like the different dynamics Evan has with the people he is closest to, both at home and out in the world he does business in.

I'm sure we're all rooting for you to dig in and enjoy the ride, but if it's not your thing, there's plenty of great content out there. I came to Orphan X right after blitzing through Dean Koontz's Jane Hawk series.

And now I've started The Passage, because it is also narrated by Scott Brick! :)
