A pride is a family of lions and a punnet is a small basket. Translation of the Queen's English for your American readers.
I suppose the terms Alpha and Omega apply to lions just as they do to wolves. In which case the Alpha is the leader, the biggest and strongest and the Omega is the runt.
Interesting start for a story about 'shifters' (mythical beings who can appear in either animal or human form, usually werewolves, but here obviously lions ((werelions?)) not specified whether African type or American mountain type (werewolves are greatly effected by the phases of the moon – are lions as well?). Tanner is our hero and was the Alpha in training of his pride, but his father, the former Apha, died before Tanner was invested. Milo and Trek are his two besties, and are alphas in their own right. Tanner is gay and admits it to himself, but apparently every other member of the Pride is aware of his orientation.
I am sure some of my basic confusion will be taken care of in following chapters.
