The useful verdict

Why Dinosaurs Before Dark works

Jack and Annie find a treehouse full of books and land in the Cretaceous. Ten short chapters, one line drawing each, and a fixed formula the child learns in book one and then applies to all the rest - which is exactly why it works as a first solo novel: the second book demands no new skills.

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.

Themes: time travel, dinosaurs, siblings, adventure, books.

Straight answers

Questions parents ask about Dinosaurs Before Dark

How long does it take to read Dinosaurs Before Dark aloud?
About 43 minutes at an unhurried pace, from a word count of 4,737. Reading it fast shaves perhaps a third off; stopping for questions on every page can double it.
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.
