Action Book Cover Design (Evoking urgency)

Visuals: A sleek black background with a subtle gradient towards the center to create depth. Gold geometric lines radiate outward from a central, stylized golden clock icon placed just above the book title. The clock icon incorporates minimalistic accents, such as sharp triangles or rectangular markers, to add a modern edge. The title "1000$ em 7 Dias" is centrally aligned and in bold, golden modern typography, creating strong contrast against the dark background. Thin, diagonal golden lines frame the top and bottom edges, giving the design structure without clutter.

Typography: A sans-serif font with clean, modern lines such as "Montserrat" or "Avenir Next" is used for the title, with a bold style for emphasis. The subtitle (if included) would use a lighter and slimmer variation of the same font family, ensuring consistency.

Layout: The golden clock icon is centered at the top of the cover, followed closely by the main title, which is arranged in two lines "1000$" on the first line and "em 7 Dias" on the second. Golden lines accentuate the top and bottom of the cover, framing the content neatly. The text is perfectly balanced with the use of empty, negative space around it, reinforcing an elegant and minimalistic aesthetic.

Explanation: The black and gold color scheme immediately communicates luxury, urgency, and a sense of wealth, which is appropriate for the extra income genre. The golden clock subtly implies a race against time, which aligns with the concept of earning money in just 7 days. The minimalistic geometric lines and sharp typography enhance the action-oriented feeling while maintaining a professional aesthetic. The choice of matte black with metallic gold foil adds a tactile and visual richness, helping the book establish itself as both high-quality and high-value.
