Our son turned 6 this year and these are the books that he loved.
Step Into Reading is a structured series of books by Penguin Random House for preschool and elementary school kids. Our son was able to read the Level 1 (Ready to Read) books in this series, which is meant for Preschool - Kindergarten kids. We found these books to be perfect for someone who has just learnt to read that year - which is what happens in US kindergarten.
This is a series of 4 books revolving around Murilla, an aspiring jungle detective gorilla living in an African rainforest and her crime solving adventures. The books are written by Jennifer Lloyd and illustrated by Jacqui Lee. Murilla is no Sherlock Holmes though, and as she trips and bumbles through the plots, she provides laughs all along the way. These simple crimes all happen in the Mango Market, with a familiar set of African animals who sell and buy stuff there. The plots, characters and fun are all reminiscent of the The No. 1 Ladies Detective Agency series. It was also refreshing to read books that are not set in the US for a change.
