Thanks for the help. I decided to read the Crystal Variation before Balance of Trade. I've been away for a few days, and didn't get a lot of reading done, but I started Crystal Soldier and so far I'm enjoying myself
It's two years since I finished the Department of Interior arc, and I know I've forgotten a lot of what was written about Jela, Cantra and the Tree. Hopefully most of it comes back to me as I get back into the liaden universe.
