Gradient Romance Book Cover Design (Evoking romance, grey, and slowburn)

The cover is split vertically into two halves. The left side is a stormy grey gradient, symbolizing mystery and lies. The right side is a soft white, representing purity and loyalty. A subtle gradient runs between these two shades to create a seamless transition, representing the "slow burn" romance and blurred lines between truth and deceit. On the grey side, faint silhouettes of intertwining rose vines with small thorn details extend downwards. The white side is kept minimal, with delicate lace-like patterns in the background, signifying fragility and fidelity. The tagline "She was loyal but her lies weren't" is elegantly integrated along the bottom edge of the gray-to-white gradient.

The title "Loyal Lies" is displayed in a serif font with elegant yet sharp edges, symbolizing sophistication and tension. It is sized prominently and centered, split across the gradient divide. On the grey side, the letters fade slightly into the background for a mysterious touch. The author’s name, "Siddhi Kadam," is written in a smaller, minimalist sans-serif font below the title. The tagline is written in a flowing script font, creating a contrast with the serif title.

The title is positioned in the center, split between the grey and white sections. The subtitle is emphasized along the lower gradient edge, creating balance. The author’s name is smaller and subtly placed at the bottom right. The textured rose vines occupy the left half, balancing the plainness of the right.
