One True Mate Series Bundle, Books 1-4

This is a story about "shiften" in a world called the Ula, which is our world, but with four secrets: the wolven, bearen, felen, and foxen. Humans do not know these shifters exist, even though these same humans are constantly guarded by an all-wolf-shifter police department.  Their females are gone, but the One True Mate Prophecy matures NOW.
