Detailed Review
The description introduces Tom and his paranormal pet goldfish with hypnotic powers who team up to foil an evil scientist older brother. The listing published by Square Fish on October 10, 2017 includes three books in a boxed set and gives a reading age of 7 - 9 years marked as from customers. However, the listing leaves print length unstated and marks grade level as Preschool -, an obvious listing contradiction for a chapter book meant for ages 7 to 9.
Who it's for: readers ages 7 to 9 who enjoy wacky humor, comic illustrations and villain-thwarting stories. Who should skip it: buyers who need verified page counts or readers looking for realistic fiction.
Its Shelf Score of 7.4/10 comes from fit 28/35, contents and edition 18/25, value 21/25 and reading age or level 4/10.

How we scored them
The Shelf Score weighs fit for young readers, contents and edition, value, and the listed reading age or grade level where one is given. All five listings provide a customer-listed reading age, and all five list a grade level, ranging from primary grades through grade 7. Titles with aligned grade levels and clear page counts score higher on contents, while unstated page counts or contradictory grade levels reduce the total. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| The Wild Robot by Brown | 9.0 | 33 | 22 | 21 | 9 |
| Matilda by Dahl | 8.6 | 32 | 21 | 20 | 9 |
| The Secret Zoo by Chick | 8.4 | 30 | 21 | 19 | 9 |
| The Never Girls Collection by Thorpe | 8.3 | 29 | 19 | 22 | 9 |
| Zombie Goldfish Boxed Set by O’Hara | 7.4 | 28 | 18 | 21 | 4 |
Scores run from 0 to 10. 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 chapter books for kids
Check reading ages and grade levels
Amazon listings often display both a reading age and a grade level, but their sources differ. For example, The Wild Robot lists grade level 3 – 7 alongside a customer-listed reading age of 7+ years, while Matilda lists grade level 3 – 7 with a reading age of 6+ years marked as from customers. Checking both numbers helps parents find books that match a child’s reading maturity. In some cases, listing details conflict, such as the My Big Fat Zombie Goldfish boxed set listing grade level as Preschool – despite a customer reading age of 7 – 9 years. For more reading recommendations by age, see our list of books for 10 year olds.
Standalone story or series commitment
Standalone novels and series starters serve different reading habits. A standalone book like Matilda provides a self-contained story of 240 pages without requiring further purchases. Series starters such as The Wild Robot (Book 1 of 3) and The Secret Zoo (Book 1 of 6) introduce ongoing character arcs and fictional worlds that carry into later volumes. Choosing a series starter gives an enthusiastic reader an immediate next step once the first title is finished. You can also explore our guide to chapter books for children.
Page count and book length
| Book | Pages | Format |
|---|---|---|
| The Wild Robot | 320 | Illustrated novel |
| Matilda | 240 | Standalone novel |
| The Secret Zoo | 320 | Series starter |
| The Never Girls Collection | 128 | Boxed set (4 books) |
| Zombie Goldfish Boxed Set | Not stated | Boxed set (3 books) |
Print lengths differ substantially across chapter books. For children transitioning into longer reading, a 128-page boxed set like The Never Girls Collection keeps individual installments brief and manageable across its four books. Readers with more endurance can tackle 240 pages in Matilda or 320 pages in The Wild Robot and The Secret Zoo. Some listings leave page counts unstated, as with the three-book My Big Fat Zombie Goldfish collection. See more options in our roundup of books for kids.
Illustrated pages and boxed collections
Illustrations offer helpful context clues for young readers building reading confidence. The Wild Robot incorporates interior artwork throughout its 320 pages, and the My Big Fat Zombie Goldfish boxed set pairs text with comic illustrations across three stories. Boxed collections also bundle multiple adventures in one package, providing extra reading material for eager readers.
Before you buy
- Check whether the listed reading age is marked as from customers rather than publisher guidance.
- Verify series position on the listing, such as Book 1 of 3 for The Wild Robot or Book 1 of 6 for The Secret Zoo, to ensure you start at the beginning.
- Look for stated page counts on boxed sets, noting that some listings leave print length unstated.
- Review listed themes in the description for peril, school conflict or sibling disappearance before purchasing for sensitive readers.
