By the Sea of Sand — Megan Hart

Their love is a memory too dangerous to recall.

Life is not easy by the Sea of Sand. The remote outpost and its lighthouse were never meant to serve as a place for wounded soldiers to recover, but that's what it has become. Teila has lived in the lighthouse for her entire life, and now she also takes care of the men and women who gave their sanity fighting the Wirthera's hive mind.

Captain Kason Reed was willing to give his life for the Sheirran Defense Forces, but now he can't remember anything except bits and pieces of the war. When his attraction to his caregiver, Teila, causes him to make advances toward her, she becomes the aggressor, urging him with her body to explore the memories of his past -- memories that all seem to draw him back to Teila…

Those returned by the Wirthera never come back whole. Their bodies are flooded with nanobots designed to trigger homicidal rage when the soldiers remember what happened to them. No matter how much Teila wants her new patient to remember her and the life they shared, before, she can't remind him.

If she does, he might kill them all.
