My sister Emma and I were mated to the most powerful Alpha twins in the North—Evan and Lucas. After the marking ceremony, they spoiled us rotten. Every she-wolf in the Pack was jealous. But they didn't know that in my previous life, when I was five months pregnant and attacked by rogue wolves on my way to a prenatal checkup, my mate Evan was taking care of another sick she-wolf. I contacted Evan ten times through mind link, but he said impatiently: "Aria, how many more times are you going to play this trick? Sophia just had a premonition this morning that there would be no rogue wolf attack today! Sophia has already coughed up blood from overusing her precognitive abilities! As the Luna, you're not helping, and instead you're here being jealous?" Sophia was a she-wolf that he and Lucas rescued three months ago while patrolling the border. She was delicate and pitiful, claiming she could foresee the future. Soon, she successfully warned of several small-scale attacks. Evan and Lucas treated her like a treasure, doting on her. My sister Emma saw this scene on her way to pick up her three-year-old nephew Noah from school. She rushed forward without hesitation to save me. She and Noah begged Lucas for help, but Lucas was even colder: "You two sisters are really something. It's bad enough you conspired to put on a show to force us to come home, but you even taught a three-year-old child to lie!" Finally, the rogue wolf pack caught up with us. Three-year-old Noah was brutally bitten to death, and my child was ripped from my womb. When I opened my eyes again, Emma and I were back an hour before the rogue wolf attack. This time, Emma and I had only one thought: to sever the mate bond.
