Jax isn't happy that his mama dropped him off with an old lady he has never met. And then it turns out Ma is a witch and has a bag of dragons to deliver to a magical dimension. While Jax agrees to work with Ma as her assistant for the day, things don't go exactly as planned. First they don't make it to the magical world but to the past in the time of dinosaurs instead! And then Ma and Jax get separated and Jax is left on his own with the dragons. He gets help and eventually finds Ma again, but of course things still don't go to plan.

This was a fun fast read. I liked the urban setting of Brooklyn and enjoyed the fact that Jax got to meet a variety of different people, including his grandfather. There are a lot of unanswered questions at the end of the book and it sets up the sequel very nicely.
