Animals and Ecosystems? Ooh, nice!

And Rim Expeditions? Is this, I wonder, the project connected to the fleshing out of Storr Sector on Traveller Map?


Cosmic Mongoose
Can I confirm that Aliens of Charted Space 3 is actually the 9th book in the Charted Space series? I thought it was Secrets of the Ancients which I am sure was released beforehand. It may affect my next purchase!


From my library, I can confirm Secrets of the Ancients is #11. I can only surmise Aliens of Charted Space is #9. And the Mongoose Publishing peeps confirmed #9 above.
