Covenant (Sojourner #2)

Lev Walker has fulfilled his purpose in Elizabeth Moon's life, but it has come at a considerable price. The bullet meant for Elizabeth has shattered Lev's mortality and the forced separation from Elizabeth has scarred his spirit, so much so that Evan Walker has purged Elizabeth's memory in order for Lev to start over. Yet love is eternal. What began with a saving Elizabeth's life continues in healing Lev's spirit as he is forced to remember what he has lost at the risk of everything.
