Summary:

Natasha Winterpike has just found out who she really is: a shape-shifter. A shape shifter can choose when, and where, they want to Shift, influenced in their change by naught.
She knows she can't let anyone know, lest she be deemed crazy and sent away.
But all of that changes when she finds out that she isn't the only one that is a shape-shifter: Three of the most important people in her life are, too.
She travels to California to join the countless other shape shifters in the world,on beautiful Isle Royale, and she joins one of the four Packs.
But a new danger lurks: The Dark Fang, a group of lethal and evil werewolves that can change only after being bitten by a Black Fang at sunset exactly.
They will stop at nothing to destroy all shape shifters.
Will Natasha be able to face all odds and destroy the Black Fangs once and for all, with help of her Pack and the others? Or are they keeping secrets as well?
And most importantly, who lives?
Who dies?
