Mystical Book Cover Design for 'Anos Não Apagam o Que o Riacho Esconde'

Create a moody and mysterious book cover for a novel titled “Anos Não Apagam o Que o Riacho Esconde.” The background should feature a dark and atmospheric river scene, with a winding creek that disappears into the distance. The riverbanks should be shadowy and slightly overgrown, suggesting a sense of secrecy. At the end of the creek, include five silhouettes of people standing together, their features indistinct, evoking curiosity about their identities. The overall color palette should consist of deep blues and greens, with hints of fog or mist to enhance the eerie atmosphere. The title should be prominent but not overpowering, possibly placed at the top or center of the cover.
