From publisher blurb: Pegadas misteriosas estão surgindo na praia, os moradores próximos estão ficando agitados. Rumores de tesouros e perigos correm. Quem está andando na areia? It's been a few months since the beach that used to be calm has been bustling. Residents of the nearby town say they see shapes and bustle on the sand when night comes, and when they go to check it out at sunrise, there are only tracks and footprints that the wind quickly hides. Then comes the rumor that they are the souls of an old shipwreck trying to return home and that they ended up getting lost on the beach for not finding the right way. The local innkeeper is interested in this curious fact and intends to discover this mystery by paying whoever dares to investigate it, as his father was one of those who suffered in the marine accident.
