This was such a fast paced read, which I was surprised by just how quickly I flew through this. Once I started this I just couldn't put it down. I was captivated and intrigued to where the story could go. 

With four estranged siblings having to come together to find The Ivory Key. Even though they all have ulterior motives for why they want the key. 

I really enjoyed the dynamic between the siblings. They all have reasons they have issues with each other but still protective soon as something happens during their journey. 

I do think Raman spent a little long on the set up of the journey. Meeting each siblings and bringing them together again took up majority of the book. But I did really enjoy seeing where each character was before the journey started and why each one is really going on the journey. 
But then once the journey actually starts there wasn't much time left. However this part still fact with story and development, not just of the characters relationships with each other but the world itself. 

I'm left wanting the next part of the story to see what happens next.
