I just received a bunch of email from eReaderiQ telling me that a lot of Poul Anderson books are discounted. There are too many to list their links, although the Polesothecnic leagues is out and Ys is also not on offer (probably not Open Road Media). But you can get (this is only a partial list):
- Fire Time
- Avatat
- Orion Shall rise
- The merman children
- After doomsday
- Starfarers
- The stars are also fire
- Hrolf Kraky saga
- The broken sword
- Three hearts and three lions
- A midsummer tempest
- World without stars
- Orbit unlimited
- Vault of ages
- There will be time
Try to browse "open road media poul anderson". There may other authors I am not aware of, it might actually be an Open Road Media sale; anyboy better than I am in browsing may help.
