The first half of the book was about just character introductions. Each chapter was from a different characters POV and there are 5 main POVs and about 4 or 5 others sprinkled within the book. 
It wasn't until there was a quarter left of the book that I felt the action started. I don't understand the motive of why The Game had them do some of the things they did. 

This book took me on a ride.

This follows 5 people whose loved ones have been kidnapped, they must play a mysterious game where the rules and game master are all a mystery to get them back. 

I thought this book was going to be more fast-paced than it was. I think that was my main issue with the book as a whole. It felt like there were a lot of bits, especially in the beginning that dragged a little and at times I did find myself skimming.

Despite this, the plot was absolutely worth it. The twists and turns it gave were insane and the ending I was not expecting at all. It also made a lot of sense, there was no point during the ending where I thought it came completely out of the blue.

I did have questions that I don't think we're addressed at all or very little at the end as well but honestly, that's me being a little nitpicky. 

The characters I didn't feel too much for and for some didn't particularly like but I felt that it didn't matter or mattered very little to my enjoyment of the book. I didn't need to like everyone to feel for them and I think that's impressive to a point.

Overall I loved the ride this took me on and I would recommend it as a decent thriller.
