Currently available (but I read via an online reader copy), Monster Locker Volume 1 is a fun book that is a bit predictable for adults, but for at least 8 and up (more 10 to 13 perhaps) this is going to be a neat adventure. A mostly diverse cast of characters allows us to see a family following traditions but also forgetting its past. Then magic happens (cue a magic cell phone, a typical kid, and some ancient goddesses) and chaos happens. This is all because of Pablo, who wants a cell phone so much he doesn’t notice all the red flags and that the oily ghost that is living in his locker is no place to be seen.
Author Jorge Aguirre and illustrator Andrés Vera Martínez take action, humor and friendship and make a story that is relatable, even if the Aztecan goddess Coatlicue hasn’t attacked your town and turned everyone into animals. 
Overall, this is a nice book. Nothing to go WOW over, but enjoyable. The theme itself has been done before, but the modern additions help make it new. The colors and details are typical of a younger graphic novel (bright colors with medium to busy details) so even there we are not getting a “fresh take” but a familiar, cozy atmosphere to things. The settings do not differ much as we just have the school pre-monster attack, and the school post monster attack, with the home of our Not a Hero But the Kid that Showed Up.
The extras include vocabulary and a pronunciation guide, along with information about the people, places, foods and creatures mentioned in the story. I knew some of the information, but most of it was new for me. I researched to see how close the statue of Coatlicue was and it was good. Therefore, I felt comfortable saying the author and illustrator have a deep connection with the material and I want more from them.
