Cover. The cover was bright and it grabbed your attention. Didn't have any issues with it
Is the story plot or character driven? The characters and the plot had equal focus. The children's adventures were vital to the story and so was their reaction to what was happening around them.
How would the book have been different if it had taken place in a different time or place? I think India made for a very interesting read. All their different Gods and beliefs gave the book an interesting hook.
Disclosure: I received a review copy of this book from the author.
