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

The second 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.

Hi, I’m Oliver! Writing a book has made me kind of a celebrity around school – no big deal. But does that mean everything is perfect? No way!

I’m still trying to figure out the usual stuff: school cliques, weird family, and how to finally win the science fair. While I may know EVERYTHING about space, there’s a lot to learn about the planet we live on, like:

• volcanic burps and bacteria farts
• how the Earth’s layers are like boba tea
• aliens! (Are we the aliens?)

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.
