You will need to have read at least Mercy and Havoc before reading Lock to get the full effects, as things with Ember did start back in their books.

I won't lie - it did take me a little while to get into Lock, and it wasn't until about 45% that things really did kick off for me - however I think this is probably just me, and end of year book blogger weariness and not the book.

This does start out as a sweet college romance, however it does not take long for things to turn darker, however with Ember being Nix/Mercy's sister, it should not really surprise you.

To me, this book should have been called Ember rather than Lock, as I felt we got so much more of her than Lock. I loved the journey Ember takes in this story, and whilst yes it is a lot of .... Lock it is more her story.

But this is just me.

I don't want to give anything away, as I feel that this is a story that you need to immerse yourself in , heart and soul.

You will be taken on one hell of a ride with this lot!

Buy it. Love it.
