A pregnant grieving widow. A protector bound by duty. And a lie that could destroy them both.

After Maddie's husband is murdered under mysterious, supernatural circumstances, she's pulled into a world she wants nothing to do with?one ruled by ancient powers and deadly secrets. Assigned to protect her and the child she carries, Lyzender is a Power sworn to duty above all else. Stoic and watchful, he'll do whatever it takes to keep Maddie safe, even if it means deceiving her.

Maddie doesn't trust him. She doesn't trust any of them. Especially not after discovering an ancient scroll that marks her as a twin soul, part of a prophecy she never asked for, and the next target of the rogue Power who killed her husband.

As painful truths about her late husband unravel, and Lyze risks everything to protect her, Maddie begins to question everything she thought she knew?about love, about fate, and about the man who stands between her and annihilation.

In a world of betrayal and otherworldly war, one woman's strength?and one warrior's vow?may be the only thing that saves them all.
