Sacrifice
When Rajiv is attacked by a giant bhimkay spider, his rescuer, Leyta, becomes his captor. Can high-status trueborn Rajiv learn to see the enslaved escapee Leyta as more than a genetically engineered non-human, or will he seize his chance to recapture her and have her brain and her very soul wiped away? Set in the Tankborn Trilogy universe.
