Couldn't put this series down. Fast paced with a colorful cast of characters and settings, plus an ending that left me with feelings. I really liked how quickly the story moved along, almost like i was watching a tv episode. I like how unique each of the brothers are and it was nice touch that one of them had to use sign language to communicate. This is a great series and i think it is geared towards the tween population who enjoy adventure stories like Percy Jackson and the fable haven series.
