Captivating Book Cover Design for '(Undying)' - A Supernatural Romance

My book is a supernatural romance set in modern-day Portland, Maine, revolving around a young woman,, and her connection with a man, a ghostly figure trapped in the mortal realm. The book has a slow-burn, enemies-to-lovers vibe with a touch of mystery. The tone is dark yet romantic, with moments of tension and longing. I would like the cover to evoke a sense of haunting romance—possibly featuring a misty, eerie landscape with a dark figure in the background (symbolizing him) and a strong, determined female figure in the foreground (her). The color palette should be cool tones like deep blues and purples, with hints of silver or white to represent the supernatural element. The title is “(Undying)” by the author (Loren Mercer) , and I’d like it to have an elegant, yet bold font that stands out, giving it an iconic feel.
