The owner of the Dallas Guns, the local arena football team, has been receiving threats on his life from someone he believes to be on his team. So Dallas detective Sammy Kidman gets roped into trying out for the Guns in order to uncover the perpetrator. As Sammy embraces the novelty of arenaball to the detriment of his work and family, his wife Marni loses all patience. With the connivance of society matron Dolly Threlkeld, Marni does a little investigative work of her own. What they discover about the owner’s true purpose throws her into a terrible quandary: How can she tell Sammy that should he achieve his goal of playing, it would entail a most unpleasant surprise? Sammy: Arenamania is Book 7 in the Sammy Series, which begins with Sammy: Dallas Detective. The story continues in Book 8, Sammy: In Principle.
