A sad pup

This is a story I've been writing for a close friend, but it's been agreed upon that it should be shared before it's even finished.
Aaron is a boy who lacks many friends. He only considers Orya and Yakira to be his friends. He wants close relatives, and a father, but he soon finds that he needs someone else he's missing. And after training gets serious, he finds out who it is he's truly missing.
Aaron and his friends are werewolves who are the best trainees for their age, and because of this, they go on missions reserved for older pups and trainers without fail. But when they are sent on a mission usually for clan leaders and warriors only, Aaron gets more than he bargained for.
I do not own the cover photo, it was found on Google.
