I would recommend this book for kids ages 6 and up. By I read what you write Blog post.
I really enjoyed reading Blast Off! with Gabby and Maddox. The story was witty and kept me interested the whole time. Sometimes it's nice to read a book with pictures in it :P I will definitely recommend this series to all the young bibliophiles I know. Jenna @ Goodreads.
Gabby and Maddox's adventures continue with a trip to outer space that proves that friends are the same everywhere. Sister and brother together the two meet a charming tiny alien who lives inside a minuscule planet in the outer solar system. Of course they face some challenges along the way, but Gabby and Maddox are up to it, and they help their new friend to solve a big problem. It's an exciting story with lots of twists and turns and great lessons on how people that are very different can get along and help each other. Jim Dodds @ Goodreads.
