Tear Down the Throne is the most recent in Jennifer Estep’s ‘s spin-off Gargoyle Queen series. It’s $2.99 right now in the US. I’ve read and quite liked her original Crown of Shards books (see here and here), and also the first Gargoyle Queen title, Capture the Crown. So it’s nice to see this one on sale, especially since it’s pretty recent – it just came out in May of this year.
Tear Down the Throne is $1.99 again at Kindle US, but this time, not at Kobo US, at least as of now. The link in the OP is still good….
Conquer the Kingdom is the third and final (at least as of now) Gargoyle Queen book. It’s $1.99 right now in the US.

The second and third Gargoyle Queen books, Tear Down the Throne and Conquer the Kingdom, are $1.99 right now in the US. The links in the OP (Tear Down) and in the comment just above (Conquer) are still good.
Sadly, the first book in the series, Capture the Crown, isn’t on sale right now.
