Spirit of a Champion — Nancy L. Radke

When things go wrong, it's Stormy to the rescue. She learns her brother could get killed in his upcoming prizefight against Killer Kyle, so she flies to Las Vegas to try to stop the match. Can she save her brother's life, outwit the killers trying to kill her, and win the heart of a champion, or will things prove too deadly for her? Her cousins, Perri and Hugo, drop everything to help her. A love story with a boxing background (not much boxing).
