Five years later, on the anniversary of my best friend's death, I slit Gaspare's throat at her grave. "From the very beginning, I came for revenge."

Sneak peek: "I don't believe in God, Hailey," he murmured, as his firm hands settled on my hips and lifted me from his lap, placing me onto his desk, "But... if I did, I would have thanked him for making you." A soft gasp escaped my lips as his hands slid under my college skirt, his fingers brushing on my pussy over my panties. "Damien, you are my brother..." I managed to whisper amid overwhelming desires. This felt so wrong. He emitted a husky chuckle, leaning closer to my ear, his lips brushing against my earlobe. "Correction-Stepbrother." "But-" Before I could utter a word, his hand swiftly slipped down inside my panties, his fingers landing on my bare, wet heat and just when a moan could escape my lips, his mouth forcefully met mine swallowing the scream of pain as well pleasure when two of his fingers thrust into my pussy just like I'd felt them in my dreams... *** When I was dragged across the country to Los Angeles to live with my mom's new husband and his son, the last thing I expected was for my stepbrother to be off-limits.

"She will come back," she promised. "She just needs time to sort her head out." "Not her heart?" The dry distinction made Charley wince. "I'm sure she loves you," she persisted. "She's just not ready to commit to marriage." If you just give her time, then I— Black eyebrows with a fascinating silken gloss gave her a curious look. "Are you actually standing there, Miss Jones, suggesting that I should wait for Adelina to sort her head out?" Well, was she? Lifting her chin, "If you love her—yes," she insisted. "Then you are a romantic fool because it is not going to happen." He moved suddenly, straightening away from the desk. "There is a wedding arranged for next Saturday morning, and I intend to make sure that it goes ahead." Without a bride? Charley stared at him. "You mean—you're going to find her and drag her back to marry you?" A silly kind of laugh left her throat at the very image of Adelina being dragged by this man down the church aisle, kicking and screaming. ‘No.’ Reaching behind him, his long fingers picked Adelina's letter up again—this time to fold it with slow, neat precision.
