If you haven't read it yet, purchase away. If you have and enjoyed it, now's an excellent time to recommend it to someone else. Book sales like this are a fabulous way for lesser known authors -- like yours truly -- to get their books in front of new readerly eyeballs.
And if you haven't checked out the other Strange Chemistry titles included, well, get cracking. You can buy ALL OF OUR BOOKS for less than a hardback -- for less than some trade paperbacks, even! Whatta a deal. It's only on for a while, so do not delay.
p.s. You could also add The Woken Gods to your cart while you're there and/or leave Blackwood a review if you enjoyed it and haven't. These things make authors happier than you know.
p.p.s. Psst...told by a friend that if you buy the kindle edition of Blackwood on sale, you can add the audiobook for $3.49 -- a steal!
