Hellfire,Brimstone & Whiskey

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

The Granger triplets have left the nest, one is a firefighter, one a sailor and the last is a free-spirited animal lover working with horses in California. 
One runs afoul of her battalion chief, and nearly dies. One fell for a smooth-talking con artist using her as cover for his treasonous acts and the last manages to survive a wildfire that destroys everything in its path. 
A sister finds the courage to love, another finds a man willing to wait her out, and one man...meets his match.
