I think the psychically linked soulmate thing is one of those really overused tropes and I cringe any time it's made a main selling point of the back cover blurb.

But I find myself reading the Stardoc series by SL Viehl anyway, and the Agent of Change series by Sharon Lee and Steve Miller. They throw in enough other cool stuff - medical emergencies in Stardoc, a great trading/starfaring setting in Agent of Change - that I forgive them for it. And it's usually not the focus.
