Jen Turano

Mr. Herman Henderson is also a mystery writer, but unlike the dashing heroes he pens, he prefers living a quiet life, determined to avoid the fate of his adventurous parents, who perished while searching for the Lost City of Gold.
As the list of suspects grows and sinister plots are directed at Daphne, the situation quickly deteriorates, and a revealed secret jeopardizes their newfound affection. Only time will tell if Daphne will be able to regain Herman's trust and save both their lives.
