The Sigil Makers: Borderless

This is a sequel to The Sigil Makers. Reading that one isn't necessarily needed in order to understand what's happening in this one, but I still suggest you go read that one before this.

A young smilodon called Glee lets her curiousity get the better of her, and despite her mother's wishes she sneaks out to meet the saber-toothed cats of another pack. In this pack she finds a peculiar smilodon called Killa and it appears as though the young felids have caught feelings for eachother, but how will the other smilodons react to this as taking a mate from another pack is strictly prohibited?
