Against All Instinct [EPUB ebook] 

Konta and his tribe live in a world where changing seasons bring forth increasingly dangerous creatures. Uttering as much as a sound can mean the difference between life and death.
Even in the direst circumstances, his people forge onward, determined to survive. From the calm of early spring to the relentless cold of winter, Konta’s family and tribe move with the seasons, and face dangers they could have never expected.
Headstrong and resourceful, Konta sets to overcome the seemingly impossible odds. But nothing he achieves will come without sacrifice.
