Wildest Bear by V. Vaughn

Clan witch Tally knows she’s fortunate to have married Marcel. Before the alpha of the Ouellette clan allowed it, witch and werebear relationships were strictly forbidden. And now she realizes there may have been a very good reason for the rule. Their toddler twins are shifting in a clan where that doesn’t happen until after puberty. And it’s taking place in a world full of humans who don’t know werebear exist.

While Tally could try to use magic to control her children until they’re old enough to understand the implication of spontaneous shifting, it’s not foolproof. And it’s not a chance she’s willing to take, because the humans who do know werebear exist want them wiped off the planet. Now that Tally and Marcel’s twins are a danger to the clan, Tally must find a way to keep everyone safe. But she fears that because her children are half werebear being a witch might not be enough.
