Okay, after internet research has gotten me exactly nothing on this, I come to you, other readers.

I read (and reviewed) T.A. Chappel's Mask in the Corridor a little while ago, and in the author's note at the end she mentions that she's working on a sequel entitled A Century Away. That was in 2006, and in 2007 a book called A Century Away by Chappel did indeed appear on the scene.

I haven't bought a copy yet, though, because I can't for the life of me tell if it's actually a new book or just a re-issue of Mask in the Corridor. The two books appear to have almost identical summaries about Jillian and her archaeological travails, so I'm stuck trying to figure out if Chappel's assertion that it's a sequel was still true a year later or if something happened in the interim that instead turned it into a mere new edition of the first book. I haven't been able to find any previews of it on the web, but Google Books seems to think that A Century Away is about 50 pages longer than its predecessor... but since it's from a different self-publisher (PublishAmerica instead of Mask's Authorhouse) and she could have changed the formatting, that doesn't really give me much evidence.

I suppose the smart thing to do is just to buy a copy and hope for the best, but I'm not made of pennies over here. Anybody out there already own this book who could shed some light on the situation?
