Pack Law states that if twins are born into the Alpha family the eldest must become Alpha. Under no circumstances can the younger twin become Alpha unless the older twin dies. This has never been a problem in the past, until now. Meet Katerina and Lex Archer. Twins born into their packs Alpha family. But with Katerina being eldest and stepping up to take the Alpha position from her father, Katerina is going to have to work twice as hard to prove that a female can lead a pack and be a true Alpha.
