Besides sending a new Ars Magica book (Realms of Power: Magic) to press, we also have ordered up three reprints:
Covenants for Ars Magica 5th Edition
The Mysteries Revised Edition for Ars Magica 5th Edition
Over the Edge 2nd Edition RPG core rulebook
We expect that we should have these reprinted titles back in our warehouse by early July. If you can't wait that long, you can purchase all three of them as downloads from e23 without delay.
