Someone on facebook asked for middle grade sci-fi titles and so I went through my goodreads list and came up with the following. These are only those I’ve read and enjoyed. (ETA And that I’ve seen kids read and enjoy in the last couple of years.) There are certainly many other titles out there and I do hope you will add your favorites in the comments. I stayed with titles that seem to me to be clearly science fiction as opposed to books that mix sci-fi with fantasy (e.g. Eoin Colfer’s Artemis Fowl series) or have just a smidgin of it. I also decided not to include YA books that my 4th graders read such as Suzanne Collins’ The Hunger Games and Orson Scott Card’s Ender’s Game.
Madeline L’Engle’s A Wrinkle in Time.
Adam Rex’s The True Meaning of Smekday.
Diana Wynne Jones’ Hexwood.
Trenton Lee Stewart’s The Mysterious Benedict Society.
Richard Reeve’s Larklight series.
Rebecca Stead’s First Light.
