Broken Moon by Cate Cassidy

Her whole life has been one long escape plan, but one thing you can never escape is your past.
Just survive.
That’s been Ember’s goal since discovering that a murderous realm sent a shadow monster to kill her. Her only chance at survival is to unravel the secrets of her true identity as a ruthless army of darkness hunts her down.
It will take a miracle to save her. Like four powerful wolf shifters who are willing to burn the world down to protect her.
But when the secrets of her past are finally revealed, it sets in motion a series of events that will not only test their will to survive against all odds but survive each other.
