Ten years ago, Deirdre Tombs died. When she was reborn the next day, Deirdre had become a shapeshifter who can't shift shapes. Nobody knows what animal she's supposed to be. She's definitely not a werewolf. The Alpha, Rylie Gresham, can't force her to transform like other members of her pack. Now Deirdre is considered an omega, the weakest shapeshifter in the pack—a vulnerable position when Everton Stark demands tribute from Rylie. He wants to be the dominant Alpha. The only Alpha. And he plans to make her pack submit whether they want to or not. Stark can make every shapeshifter obey him by force of will alone. Every shapeshifter except Deirdre. The shifter who can't shift is the only hope for Rylie to win the war against Stark. It will take everything Deirdre has to survive undercover in his den. But can an omega's will be stronger than that of a charismatic, deadly Alpha like Everton Stark?
