Obsidian Moon Crate is a quarterly book box based in the US that focuses on adults with interest in the darker elements of life and books. Each box comes with a new hardcover book either YA or Adult Fantasy or Science Fiction, one crystal, one candle, and four to five other items. December’s theme is Darker than the Deep.

The items included in this box are a Empire of Storms unisex t-shirt, a mixology drink, a candle inspired by Black Sun by Rebecca Roanhorse, a bath bomb with a crystal inside it, a Skin of the Sea inspired enamel pin and a set of foil bookmarks inspired by the Shades of Magic. All the items are high quality and the only one I won’t use is the mixology drink but I like the idea behind it.

The book included was The Syren’s Mutiny by Jessica S. Taylor which follows Brigid who stowaways on a ship to escape being married off, but when she is discovered she is thrown to the ocean. However, she is saved by becoming a Syren and Brigid now has the ability to seek revenge on those who wronged her. Based on the summary it sound to me like a dark fantasy horror with some possible romance. This edition also has an exclusive dust jacket, art on the hardback and end papers, and painted edges.

Overall, if you are interested in a darker aesthetic or darker book this could be the book box for you. I do plan to order other boxes from them in the future. The next quarterly boxes theme is Courting Death.
