Because I enjoyed Hounds of Autumn - Heather Blackwood, I snagged The Clockwork Cathedral when I noticed it offered for free.
There are five books in this series and over the last couple weeks each of books in the series has been offered for free for a short time. Normally I don't get additional books in a series until after I've read the first one and I enjoyed it. But in this case I grabbed them while free, in case I do enjoy this series.
Hopefully I will enjoy these books and it'll be a win-win! If not, well, at least they were free.
Currently book #4 is free. If this series looks interesting I suggest snagging that one now, and see if the others roll around to free again at some point.
