### ⭐⭐⭐⭐⭐ "Please keep writing these" - Our 11 year old
        
*by D***G on December 26, 2017*

Our 11 year old son, who is a picky reader, devoured this 2nd book in the Jack Geniuses series and can't wait for the next one.  He is a budding engineer and the series has grabbed his attention.  Nice mix of science and adventure to keep his interest.
  

### ⭐⭐⭐⭐ Great book for 8-10 year olds
