Mysteries that Matter


Latitude Zero

Latitude Zero by author Diana Renn

I have to run,” said Juan Carlos. “You will call? Please? It is very important.”

“Yes. I will call. Definitely. At two.”

That’s what Tessa promises. But by two o’clock, young Ecuadorian cycling superstar Juan Carlos is dead, and Tessa, one of the last people ever to speak to him, is left with nothing but questions. The media deems Juan Carlos’s death a tragic accident at a charity bike ride, but Tessa, a teen television host and an aspiring investigative journalist, knows that something more is going on. While she grapples with her own grief and guilt, she is being stalked by spies with an insidious connection to the dead cycling champion. Tessa’s pursuit of an explanation for Juan Carlos’s untimely death leads her from the quiet New England backwoods to bustling bike shops and ultimately to Ecuador, Juan Carlos’s homeland. As the ride grows bumpy, Tessa no longer knows who is a suspect and who is an ally. The only thing she knows for sure is that she must uncover the truth of why Juan Carlos has died and race to find the real villain—before the trail goes cold.
