The cover features Nefel and Davian standing in an intense pose in the forefront. Nefel, in a flowing, dark Victorian gown, holds a single crimson rose delicately by her side. Her crescent moon pendant gleams faintly at her throat, catching the silver light of a pale full moon. Davian stands beside her with an air of protective strength, his defined features bathed in eerie moonlight. Behind them, a gothic castle obscured by swirling mist towers imposingly, its spires piercing through a stormy, dramatic night sky. Skeletal barren trees flank the cobblestone path winding toward the characters, where faint blood droplets near a partially hidden masquerade mask add a sinister yet subtle detail. The swirling mist and shadows are accented with deep crimson hues, lending drama and passion to the overall design.

Elegant and gothic-style serif fonts for the title, rendered in a deep crimson color with subtle shadowing, create a timeless aesthetic. The author’s name “Leanna Edwards” is presented in a smaller, refined serif font in soft silver, positioned at the bottom to harmonize with the moonlight-inspired theme.

The title, "Crimson Eternity," stretches prominently but gracefully across the upper third of the cover. Nefel and Davian are centered as the main focal point, with the intricate gothic castle and the stormy moonlit sky rising behind them. The author’s name is subtly placed near the bottom center, integrating seamlessly with the cobblestones' soft texture without detracting from the characters or the title.
