I saw on Twitter yesterday, and also got an e-mail last night, that Half Past Dead, a two-novella anthology featuring stories by Zoe Archer and Bianca D'Arc is currently being offered as a free ebook over at the Sony eBook Store.
Archer's story is a prequel to her upcoming Blades Of The Rose series, which sounds like an intriguing mix of Victorian historical, fantasy/magical elements, and Indiana Jones-style derring-do.
D'Arc's story is also a prequel to her paranormal-zombies-running-amok book, Once Bitten, Twice Dead - which is out now in trade paperback.
I've done a very brief search, and it appears that Half Past Dead is only available as a free ebook at the Sony Store. Also, no idea how long this promotion is going to last, so if you're interested - strike while the iron is hot.
You can download it here.
And neither here nor there - I read a previous Zoe Archer book, Lady X's Cowboy, back in my TRR days and really liked it quite a bit.
