How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level where one is given. All four listings state a reading age and a grade level. Three of the reading ages are marked as from customers; The Smartest Kid in the Universe lists 8 to 12 with no such mark. How we pick explains the weights.

Book Shelf Score Fit /35 Contents /25 Value /25 Age/level /10
A Rover’s Story by Warga 9.7 32 21 20 9
The City of Ember by DuPrau 9.7 30 21 20 9
Smartest Kid by Grabenstein 9.7 29 20 20 9
Hatch by Oppel 9.6 28 19 19 9

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best science fiction books for middle school

Start with the series position

Two of these books open a series and one continues one. The City of Ember is Book 1 of 4 and The Smartest Kid in the Universe is Book 1 of 3, so both give a reader somewhere to go next. Hatch is Book 2 of 3, so buy the first book before this one.

Match the age band to the reader

The bands run from 8 and up on A Rover’s Story to 10 to 13 on Hatch. Grade levels run 3 to 7 on three books and 5 to 6 on Hatch, which skews older. For more choices by level, browse our middle grade books.

Check the length against the reader

Hatch is the longest at 416 pages, and The City of Ember is the shortest at 288 pages. A reluctant reader may finish the shorter book first and come back for the longer ones. For shorter sci-fi options, see our sci-fi books for middle school list.

Before you buy

  • Check the series number: Hatch is Book 2 of 3, so confirm you have the first book.
  • Compare the listed reading age with your reader, and note when it is marked as from customers.
  • The descriptions here include peril and alien threats; preview for a sensitive reader.
