Pregnant By My Best Friend Alpha

Kyra caressed her growing belly—she was finally pregnant with her best friend Nathan's child after three years of marriage. But when she returned home with the happy news, her Alpha husband was on his knees, begging her to end their bond.
"Sophia is back," Nathan’s voice raw with guilt. "My fated mate."
Heartbroken, Kyra agreed to dissolve their union, hiding her pregnancy to avoid burdening him. Yet when she tried to leave, Nathan refused to let go. "Can't we at least stay friends?"
She wrenched her wrist free. "You lost that right."
Nathan didn't understand these feelings until Kyra was gone and then he knew this wasn't just friendship. This was love. And he'd fight to get her back.
Then he appeared—Kieran, Kyra's stepbrother and the infamous Alpha from Raven Shadow Pack. He kept her captive, craving every inch of her.
"We're siblings,"Kyra gasped.
His teeth scraped the mating mark on her neck as he growled."'Not by blood.Run from him all you want, little wolf. But you belong to me now."
Trapped between two impossible loves—where does Kyra truly belong?
