Underworld Fanfiction Crossover Novels & Stories

In the Corvona underworld, there is one unspoken rule. When a Don keeps a new woman by his side for three consecutive months, the Donna must personally remove the signet ring symbolizing her power and place it on the new woman's finger before the entire family. When my husband, Luca, the Don of the Bellini family, announced he would take Mia alone on a three-month business trip, the entire Corvona underworld waited for me to have a meltdown. I had been with Luca Bellini for seven years. I followed him everywhere, refusing to leave his side. I would even wake up in the middle of the night to touch him, needing to know he was there to feel secure. They were all aware of my clinginess and were betting I would never let go. But when Mia extended her hand to me, her voice dripping with saccharine, I didn't shed a single tear. I calmly removed the signet ring engraved with the family crest and slid it onto her ring finger. Luca, lounging in the leather chair at the head of the table, swirled the whiskey in his glass, satisfaction gleaming in his cold blue eyes. "Elara, you've finally learned your place." I lowered my gaze to my bare finger, saying nothing in return. What Luca didn't know was that a month ago, I had recovered all seven years of my lost memories. I wasn't some street orphan at all, but the long-lost Principessa of the Rossi family, the most powerful of the Old World families. In three days, my brother's armed convoy would roll into Corvona to take me home.
