Genre Covers

4 prompts

Romance Cover Design

1/20

Romance book cover. Subgenre: [contemporary / historical / paranormal / romantic suspense].

💡

Pro tip: Fantasy covers = atmosphere + scope. Dark epic fantasy: moody + singular symbol. Urban fantasy: contemporary setting + magic hint. Specify subgenre for right aesthetic.

Thriller/Mystery Cover
