Pendulum, was an okay book. I felt that there was too much romance and too little action. Overall, the characters were well-developed and the storyline was well-executed. The action-packed scenes were well-written and exciting, but too few, leaving the entirety of the story drowned in romance. To love-sick girls, this is a good book, but to a teenage boy like me, it is boring and uneventful. I also wish that the characters spent less time in a submarine and more time fighting the queen. In total, the book didn’t meet my expectations and there were many areas where there could be more action and excitement.
