Free book online

Recently I started reading books by Sherwood Smith. I thoroughly enjoyed Crown Duel and Court Duel, so I read the Wren series. Sadly, the fourth book in the Wren series has yet to be published. Yesterday, to my delight, I discovered the author had put the fourth book, Wren Journeymage, online. I just finished reading it. A very nice ending to a great little fantasy series. Thank you, Ms. Smith!
