Work in progress – New crime book for kids

I am currently working on a new book series with the to characters, Rosa and Marie. It is a series of light crime stories, and the two girls get involved in different cases, which may look very scary at first glance.

The stories are written by Per Østergaard, and he is also the creator of another book series with the young detectives, CLUB4. 
And the publishing company is TURBINE
