Sal and Gabi Fix the Universe, by Carlos Hernandez, (May 2020, Rick Riordan Presents), $16.99, ISBN: 978-1368022835
Ages 8-12
I finally got to read Sal and Gabi Break the Universe for the 2019 Cybils earlier this year, and WOW. I loved it all: the Cuban-American characters and cultural references; the great storytelling and witty dialogue; the wild magic-meets-science; the overwhelming power of family, in all its forms, that comes through the story. When I had the chance to read an advanced reader copy of the sequel, Sal and Gabi Fix the Universe, I jumped for it!
You had to know, if you read the first book, that Sal and Gabi’s second adventure is even more fun than the first. Avoiding spoilers, I’ll just say that events in Break the Universe have reverberations in Fix the Universe. Sal’s calamity physicist father and Dad: The Final Frontier, one of Gabi’s dads, have been working on a machine that can fix the wormholes Sal creates. This causes some problems, as a rogue alternate Gabi arrives on the scene to warn Sal about. Meanwhile, bully Yasmany has gone missing from school, adding another mystery for the two to solve. American Stepmom, the Gabi-Dads, and Principal Torres are all back, joined by Rogue Gabi and a self-aware bathroom. There’s more non-stop action, hilarious dialogue and more creativity from the Culeco Academy crew as they work to put on a school show in the middle of everything. Buckle up and enjoy the ride.

You know I also fell in love with Sal and Gabi after reading book one for Cybils, haha. I just finished this sequel a couple weeks ago. I agree that this book builds on what I loved in the first one.
