Outrageously gorgeous blue aliens, electric football, and a heroine with a massive chip on her shoulder are the main components of Jordan's pick of the week: "Blade Dancer" by S.L. Viehl.
This is sci-fi (romance) in all of its tropey, laser-gun glory, but there's also an assassin school, a tragic family history, and enough emotional conflict to keep the relationship building until the very end.
