I'm trying to find affordable copies of this trilogy by Linda Proud.  The titles are "A Tabernacle for the Sun", "Pallas and the Centauri", and "The Rebirth of Venus."  Thought someone here might have a lead...
 

I know you're looking to buy, but if you want to read the books while you await afordable copies, remember the library ...

Genie, thanks.  The library is always a great suggestion!  Unfortunately the books aren't available in our countywide library system. 

Donna, have you asked about interlibrary loan?  Many libraries will do this.

Well, I do this all the time within the county-wide network.  I will have to check and see if they are able go outside the network.  Worth a try!

@Donna, they should. You may want to ask if there's a charge. My local library does not charge for out-of-network ILL, but some do.

Thanks, Genie.  I'll let you know how I make out.

I've received ILLs from all over the US. Even college libraries and once from the library of a Benedictine Abbey. Only once was I asked to pay a lending fee.

@ Cathy, Good to know, thanks : )
