Reading a book in French can be challenging and that is why I recommend you to start with an easy reader with many repetitions and high frequency vocabulary.
" Jean-Paul et ses bonnes idées " is a good one to start with. It is repetitive and simple and uses many cognates and high-frequency words to make the book comprehensible to beginning to intermediate adults and children.
Jean-Paul is an 11-year-old boy who lives in Paris. His best friend is Pascale. Poor Jean-Paul has one big problem. He does not like school. He does not like to study or do homework. Fortunately- Jean-Paul has a lot of good ideas. He thinks of many fun and exciting things to do rather than going to school.
