About The Book

‘Mind-expanding and hilarious!’ Jeff Kinney, author of the bestselling DIARY OF A WIMPY KID series.

The third book in the hilarious series that makes you laugh-out-loud AND grows your brain. Perfect for readers age 8+ and fans of Diary of a Wimpy Kid and The 13-Storey Treehouse.

Oliver needs a new computer – and has a brilliant idea of how to get one: write another book and sell it at school! So, he picks a topic he thinks lots of kids will like – animals. But then when he starts to think about it, he wonders where do animals come from, and that leads him to wonder where life comes from and how animals – oh yes, and people – evolve . . .

From bestselling writer and robotics engineer Jorge Cham, Oliver’s Great Big Universe: Volcanoes Are Hot! is the second book in a STEM-themed, diary-style series.
