Our review

The structure of this book is very helpful for new readers. Once they learn the pattern in the first book, they can apply it to all the others, which builds immense confidence.

It suits children who love dinosaurs and adventure. It is a great starting point for a long-running series.

Before you buy it

Jack narrates by taking notes, which slows the middle; children who want dinosaur action get more note-taking than chasing. The series has thirty-plus books plus non-fiction companions and the numbering confuses parents—this is book one of the original set.

Questions parents ask

How long does it take to read Dinosaurs Before Dark aloud?

About 44.5 minutes at an unhurried pace, including a standard allowance for page turns, pictures and participation, from a word count of 4,737. Stopping for a longer conversation on every page will add more time.

What age is Dinosaurs Before Dark actually for?

Ages 6-8 in our testing, which is narrower than the publisher's range. With 4 sentences a page and vocabulary at 3 out of 5, it asks for that much attention span and no more.

Does Dinosaurs Before Dark survive being read on repeat?

Yes, reasonably. It stays bearable through the repeat-request phase without becoming a favourite forever.

Is Dinosaurs Before Dark a good book for a child who will not sit still?

It helps that it has a refrain a child can join in with. Those three features are what keep a wriggling toddler listening, far more than the subject matter does.

Will my child memorise Dinosaurs Before Dark?

Probably, and fast. The book leans on a repeated refrain, and at 3 out of 5 for re-read tolerance it survives the nightly repeats that get a book memorised. Expect your child to chant the pattern back before they can actually read.

Can a beginning reader read Dinosaurs Before Dark on their own?

Not yet. At vocabulary level 3 out of 5 and 4 sentences a page, it is a read-aloud book rather than a first solo read. Read it to them now, and hand it over in a year or two.

Is Dinosaurs Before Dark part of a series?

Yes, it belongs to the Magic Tree House series. It stands on its own, so you can start here without reading the others in order, then move to the rest if it lands.

What themes does Dinosaurs Before Dark cover?

We tag it with time travel, dinosaurs, siblings, adventure and books. Those are the threads that actually run through the book, not just the ones on the cover, which is how it earns its place on our themed lists rather than a keyword match.
