Mech warrior, dark age

"Lieutenant Travis Long of the Royal Manticoran Navy is one of those rare people who likes rules but has a talent for thinking outside of them when everything starts coming apart. That is why he is now a mustang and also why he has enemies. At the moment, there are powerful forces in the young Star Kingdom's Parliament who don't think they need him or the navy for that matter. Unhappily for them, the edge of the explored galaxy can be a far more dangerous place than they think. They're about to find out why they need the Navy...and how very, very fortunate they are that Travis Long is in it"--

Robyn Ballantyne’s journey takes her to the land of her birth. When she returns with her brother to the uncharted wilderness northeast of the Kalahari Desert, she is prepared for grand adventure, searching for her long-lost father, and bringing the word of God to the savage tribes along the way. Soon, however, this spirited young woman finds herself wandering in a quite different kind of wilderness, equally uncharted, when she observes the superb figure of a naked man bathing on the deck of the ship carrying her toward experiences she has hardly begun to imagine. Both brother and sister are obsessed with the Dark Continent--she for spiritual reasons (or so she had thought), he for wealth and fame. Their search and their separate obsessions lead them to a race into the beauties and terrors, the vanished Eden of the African interior. For Robyn it leads to one man, whom she loves but knows she must not, and to another, whom she cannot love but knows she must.--Adapted from dust jacket.
