It seems like there are a lot of book giveaways going on right now. We all like free stuff, so in (yet another) effort to streamline browsing experiences, here is a list of the ones that I've found (thus far). I'm not going into detail with these giveaways. I figure if you are interested you can click on the link and figure it out yourself.
1. Iron King Giveaway here
2. Clockwork Phoenix giveaway here
3. JV Jones contest here
4. Finch giveaway here
5. Horus Heresy series giveaway here
6. Cold Magic contest here
7. Nessantico giveaway here
8. Temeraire contest here
That's all I could scrounge up right now. I know there have to be more out there. It seems like I've seen a ton of them on Twitter. However, a bunch are escaping me. If I've missed any, let me know and I'll update the list.
