I bought "At the crossroads of worlds" after the many positive comments that I read everywhere. But ultimately I'm pretty disappointed. I struggled to finish the book, I forced myself. The story could have been more exciting. It starts well, but gradually it becomes longuet, too "gnan gnan". The love story between Lyra and Will is too predictable. I did not like either there is too much when the author makes us his criticism of religion, I think it has nothing to do in this type of book. In short, the first volume, I liked, but the book progressed the more I got tired.
