Family Instinct | First Book in the "Majira Blackstripe" Book Series

Majira and Jasmine are siblings, and treat each other like it. They're not like the other cubs and adolescents that live where they do. They get along, very, very well.
They have been raised in the Animal Kingdom, but, all animals have. They, however, live in the town region like all the other felines. Black cats, tigers, and lions live with them. The canines live in the city region, where it's loud, and reckless, right where they belong. Wolves, and other dogs of all sorts live there. Then, there are the zoonimals, who live in the forest region. They still have access to everything us felines do, only, they feel more at home.
Then, there's the bloodhounds, the ferals, and the insane. They live in the Underworld. No feline, zoonimal, even canine has ever gone there before. It's too dangerous.
But, after a canine goes feral in feline territory, will Majira be the one to escort her to a torturous hellhole?
