Rejected by the alpha, crowned as the rogue Queen

“He rejected her on the Luna ceremony day. Now she's back, with his twins, but he doesn't know it's her... yet. When Sierra Woodsworth, the omega nobody, was revealed as the fated mate to Alpha Isaak Nightingale, the ruthless heir of the Moonbane Pack, the entire werewolf world watched. But instead of accepting her, Isaak rejected her in front of everyone for his long-time lover, the elegant but cruel Bethelina. Heartbroken, Sierra vanished, only to return five years later as a powerful rogue queen leading a hidden pack and guarding two little children, one of whom has Isaak's silver eyes. But she's not here for love. She's here as the neutral power among the powerful packs.... that is until the bond she thought was dead flares to life again. As prophecy awakens and enemies gather, Sierra and Isaak must face the truth: she isn't just his mate. She's the Last Moonborn, the key to saving or destroying them all.”
