This was a great book full of action and adventure! This book starts off kind of slow introducing the main characters and plot, but once Ethan and Tianna decide to go to Hong Kong the action doesn’t stop until the last page. There is a lot of suspense while the characters travel the world. This is a great book because it was based on the true story of Tianna’s father. I would highly recommend Nine Days to anyone who likes an action and adventure story.
