Diego was commissioned by Harper Collins Brazil, under the Thomas Nelson label, to create an atmospheric cover for "Os Clãs da Lua," a novel by Brazilian author Sara Gusella.
Set in a distant future where Earth has become uninhabitable, humanity is forced to take refuge on the Moon, where they encounter the Lunars—a race similar to humans, distinguished by their silvery skin. A delicate peace is shattered when the Lunars, fearing human advancements, establish the oppressive Lunar Empire. Centuries later, humans endure life in servitude, hoping for the fulfilment of an ancient prophecy that promises their return to Earth. The story follows Taluya, a princess of the Lunar Empire, whose life is upended as she prepares for the traditional Clan Ball. A startling truth about herself propels her into an unexpected journey, aided by a sentimental robot and a wary human named Elliot. Together, they strive to uncover hidden secrets and confront the ancient force of Gravity, a force that has chosen Taluya to change the fate of both humans and Lunars.
Diego's cover beautifully captures the intrigue and dramatic tension of this epic sci-fi narrative, blending elements of lunar mystery and adventure to entice readers into this extraordinary world.
