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. Three picks state both a reading age and a grade level; Running for Shelter states a reading age of 13 to 18 years with no grade level. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Just Mercy by Stevenson | 9.8 | 32 | 21 | 21 | 9 |
| The Disappearing Spoon by Kean | 9.7 | 30 | 20 | 21 | 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 nonfiction books for young adults
Reading age first
Check the stated age before anything else. Just Mercy lists a reading age of 12+ years and grade level 7 to 9, The Disappearing Spoon lists 10 years and up and grade 5 and up, and Running for Shelter lists 13 to 18 years. In the Heart of the Sea lists 8 to 12 years and grade 3 to 7, which sits below the young adult reader. A reading age marked as from customers is buyer-reported rather than publisher guidance, so treat it as a hint and preview the book yourself.
Memoir, science, history or adventure
Match the subject to the reader’s interests. Just Mercy is a justice memoir about the fight against wrongful conviction, The Disappearing Spoon tells science history through the periodic table, Running for Shelter is a Holocaust account, and In the Heart of the Sea is a survival adventure. A teen who loves science will finish the Spoon; one who loves history will finish the Essex story.
Adaptations and editions
Three of the four are adaptations: Just Mercy, The Disappearing Spoon and In the Heart of the Sea each have a young readers or young adult edition that condenses the adult book. Running for Shelter was written for young adults directly, by the subject’s granddaughter. Adaptations keep the story while trimming length and complexity, which is why the page counts run 174 to 288 pages.
