This book is the second book in the series and it is also one of the most intriguing and gripping books that I have ever read. It is mainly about John and how he needs to rescue Philipa from the most powerful djinn in history.
The Blue Djinn of babylon is one of the most powerful djinn. She is the one who decides who is right and who is wrong. Since there are 8 good tribes of Djinn and 8 Evil tribes of Djinn she is the one who uses logic and decides. Although
becoming a blue djinn means to give up all emotions and to have a rock-hard brain which is powered with logic. She must be very unbiased towards both the tribes as in the world there has to have good luck and bad luck. Now Ayesha is the blue djinn but she is getting old and she appointed somebody else somebody very ideal for the job although the person she appointed although disappeared very mysteriously(which you can find out in the third book). So Ayesha wants to appoint Philipa’s mother to the job although Layla Gaunt disagrees. This puts Ayesha on a very difficult position so she Kidnaps her daughter and makes her forcefully become the blue Djinn of Babylon
So John has to go to bagdad where the palace is and rescue before its too late. As the blue djinn only has 30 days before she will give in al her emotions.
I think this book really portrays the relationship about brother and sister and how anybody will go to the end of the world to save their own sibling.I also think that readers who like fantasy and adventure stories will love this book as like the first book it has double the adventure and triple the action.
