The following review is for the Spanish edition of this title, Skeletina y el entremundo. In this lovely picture book, Skeletina introduces her lively cast of friends in the world of in-between, where the living visit while they are asleep. Skeletina enjoys meeting children who are visiting and helps them get over their fears or reunites them with loved ones who have passed away. Helped along by full-color cartoon illustrations drawn with pencils, the Spanish text invitingly introduces the dreamer to creatures that are happy to teach different skills, which will help them face fears, harness creativity, or find comfort. Despite the ghosts and skeletons, this isn't scary, as the story is presented in a positive way, bursting with color and an emphasis on the fact that the world in-between can be shaped and molded however the dreamer wishes. A playful story full of Latinx cultural touchstones.

"The in-between world is the one place where the dead and the living come together," and Skeletina is the mistress of that universe.As the friendly, playful skeleton provides a tour of this space, which evokes the vibrant images of el Día de los Muertos, she explains that the living come here when they dream and describes several of its residents. Fludz, a smiling blue ocean wave, for example, helps children overcome their fear of water. Skeletina serves as a guide through dreams, helping with anxieties and warding off nightmares. Jaramillo's artwork is captivating, with details, bold colors, and intricate use of delicate grays and blacks that result in an ethereal look. The endpapers preview inhabitants of the in-between world; however, confusingly, not all of them appear in the book, and some who are featured in the book are not included there. The story reads like wisdom from ghosts ("This is a strange place indeed, but always remember you get to decide what happens next!") but also contains suggestions for pacifying spirits and taking control of dreams. While all of the pieces are connected, there isn't a tight hold on the various threads. Most characters are nonhuman, though their world is infused with references to Latinx folklore; human characters are racially diverse.
