Children's Review: The Art Detective (book 1)

The Art Detective (This Shape Becomes... Book 1) - J. Michael Skaggs, Alex Robinson
We received this book to give an honest review.
K seemed to really enjoy this book until he got to the end of the story. He did not like not finding out who the thief was. He had fun looking for clues or what he thought was clues while reading. 
In this story you are an art detective who gets put on a case to solve who has been taking I.C. Shapes art. Who is it? We never get told and where the story ended abruptly K was not please. 
Hopefully there is a book two in the works that will have us maybe finding out who exactly is behind this. There is a website at the end of the story that I believe we will be checking out to see what that has to offer. 
The paintings are very different and crazy looking which K and I thought was kind of funny. We had to wonder who would steal them though? 
I liked how there were questions being asked by you the art detective so you kind of have to think a bit.
