Murder and the Middle-Aged Cheerleaders

Trouble is afoot in the sleepy San Antonio suburb of Los Indios. 
A poolside dinner party ends in tears, as many poolside dinner parties do when the margaritas are flowing and the guests are all self-absorbed nouveau riche. 
A family business is threatened by the arrival of the greedy Irish step-cousin, whose ego and social ineptitude are matched only by his complete disregard for all things Hispanic.
A gaggle of middle-aged has-beens, living in the past, seek to relive their high-school glory through cliquish intrigue and deadly poison.
And Xandie Davenport, Tejana schoolteacher, is stuck in the middle, caught up in murder and childish politics. Can she outwit a grasping relative, sniping housewives, and a vicious killer, all before summer break ends?
