This one was a required reading for school, and immediately after finishing the school lecture, I went to my local bookstore and ordered the second book. By now, six out of seven books of the "Shadow Children" series have a place on my shelves, but as it has been so long since I've read them, I fear I wouldn't be able to get into the seventh anymore. However, at least the first three books can be highly recommended by me. While I don't remember so much about the fourth, the fifth and the sixth one, Luke's experiences and the enthralling plot in this first installment were excellent to follow, with Luke being a very likeable boy who you can't help but root for.
