I have read a few dual book series, and I like it. The length is great. You can get from the start to a finish of a story in more detail than in just a standalone book but it still feels like a standalone story. However, I like to read both books back to back. I don't think I would enjoy it as much if I had to wait a year between each book. I put up with the wait for series because most of the time there will be another book after it, but knowing you are waiting for the last installment is torturous.

I liked Severance, but not as much as I enjoyed Volition. I did get my wish- Joel was not as perfect in this book. I enjoyed seeing a more human aspect to him. And the storyline was pretty creepy. Stalkers really creep me out. I loved reading about Joel and Charlotte and seeing them overcome all the odds, but there is one thing that I just don't like in my stories. And that is babies. I know, I know- you can't believe it! But hey if that type of thing doesn't bother you, then you will probably love the book! (and for the record, I don't have a personal vendetta against babies or people that have them, I just prefer to not see them pop up in the books that I read).

I think that Joel and Charlotte's story is a compelling one. I enjoyed getting to know them, and I really liked the edge of your seat storyline in the second half of the book. I was a little worried that things would be happy go lucky for the couple and that th book would be boring, but that wasn't the case. There are plenty of roadblocks for the two to keep you turning pages. Volition and Severance is a good duaology for people that don't mind angels and a little religion.
