Stole My Heir for His Mistress: I Shattered His Pack and Crowned the Rival

"Is he back yet?" I asked, pacing the length of the grand entryway.

Mara, the head housekeeper, paused her dusting and shook her head. "Not yet, Luna. The border patrol reported his vehicle crossing the perimeter five minutes ago. He should be pulling up any second."

I smoothed the edges of the white envelope in my hand. Inside rested a single sheet of paper and a grainy ultrasound photo. Eight weeks.

"He's going to flip," I muttered.

"Alpha Caleb has wanted a pup since the day he took over the pack," Mara said. "He will be thrilled."

"I hope so," I replied, tapping the envelope against my thigh. "We've been trying for two years. He was starting to lose hope."

"The Goddess answers in her own time," Mara offered. She bowed her head briefly, then scurried off toward the kitchens, leaving me alone in the vast, empty hall.

I looked down at the envelope. My thumb traced the seal. All the late nights crying, all the doctor visits, the relentless whispers from the pack elders about my fertility—it was all over. I was finally giving Caleb the family he desperately craved.

The heavy oak doors slammed open.

I stepped forward, holding the envelope out. "Caleb, I have to tell you—"

The words died on my tongue.

Caleb stood in the entryway. His broad shoulders blocked the afternoon sun, but the shadow he cast wasn't alone. His arm was wrapped tight around the waist of a strange female werewolf. She leaned her entire body weight against his side, her fingers tangled in his shirt.

"Who is this?" I asked.

He didn't answer right away. He just stared at me, his jaw set in a hard, uncompromising line.

The stranger didn't even look at me. Instead, she pressed her face deep into the crook of Caleb's neck. She inhaled deeply, dragging her nose along his scent gland. Her eyes slipped shut in a blatant show of ownership.

The warmth in my stomach vanished, replaced by a freezing block of ice.

A sharp sting shot through my chest. The mate bond flared to life, transmitting a rush of intense, burning lust directly into my nervous system. It felt like hot needles piercing my spine.

It wasn't my lust. It was Caleb's.

And it was entirely directed at the woman clinging to him.

My fingers clamped down. The pregnancy confirmation crumpled into a tight ball. My nails dug so hard into my palms that the skin threatened to tear.

"Caleb," I said, louder this time. "Explain this."

He finally met my gaze. His eyes were devoid of the warmth I expected. "Elara. Go upstairs."

"No," I fired back. "Tell me who she is. Right now."

The female pulled her face from his neck and smirked. "You didn't tell her?"

"I just got here, Siena," Caleb muttered. He didn't let go of her waist.

"Siena," I repeated the name, tasting bile in the back of my throat. "Why are you holding her like that?"

"Because
