The Test of Devotion
The son of a dangerous outlaw, young Viajero is sharp for his age and has a strong suspicion of everything and everyone--until he is asked to act as guide for a strange, silent man with kind eyes. Henry Trevalyn claims to be an ordinary man looking for his betrothed, who ran off with someone else after hearing Trevalyn had been killed. But Viajero soon learns there's a political plot in the works and his new friend is part of it.
15-year-old Jenny Forsythe has a secret. One too many, actually. Working in a hotel in Laredo isn't easy for the daughter of an unpopular man. Fiercely defensive of her father in spite of his many faults, she is upset that he is befriending the worst sorts of people--especially a no-good outlaw who now dominates the hotel. When a grubby boy and a mysterious man show up, it doesn't take long before Jenny is part of the adventure.
Some action violence. A villain gets shot. Men drink a little alcohol sometimes and there is humorous mention of a man who is an alcoholic.
