Sal Vidón has just started at a new school, with new bullies and new teachers who don't understand his needs as a kid with diabetes. Sal also has the ability to cause rips in time and space by transporting objects from other universes. He uses this to do everything from performing clever pranks to bringing the doppelganger of his long-dead mother home for a visit.

When Sal plays a prank on the best friend of Gabi Reál – student council president and all-around go-getter — it leads to a friendship that could break the universe — or save it. Traveling between universes has never been so much fun! Your young readers will love Sal and Gabi as their budding friendship takes them on a remarkable journey through the multiverse.
