The first part of this book had me gripped and set my expectations really high for the rest of the story. 

The set up of the pact and premise for the plot was full of tension and intrigued that I didn't want to put it down! That being said, the execution of the plot itself fell short for me and felt there was so much undiscovered the potential this plot could have had which left me feeling a little disappointed. 

It's never ideal when finishing a book that you can think if multiple ways you wish the plot had taken instead to make it more intriguing and fit better along the story line itself. One of the key elements of this story was the

,does Megan remember the pact or not plot line,

which honestly felt too long winded and being re-established every other chapter. I believe the aim was to create this sense of uncertainty around it but really it just felt repetitive and a bit of a bore - especially when it is finally confirmed that

she does remember

cause it was pretty predictable from the outset in my opinion so didn't exactly make for a strong plot twist/reveal. 

I did really enjoy each of the characters and how they developed through the book and the dynamics in the friendship group shifts ... however I felt that

Megan's sudden development to becoming the hero and wanting to save her friends at the end of the book and then claiming to 'just be joking' about the favours was not only unrealistic but felt like it undid a lot of the essence of Megan's character.

Similarly, whilst I can understand

Daniel becoming the supposed villain in this story line for the plot twist -

to me it felt like an easy choice and then there was no solid explanation for this development either which was unsatisfying -

a claim to be having a mental breakdown with no explanation or foreshadowing - just isn't enough for me

.

Overall I really enjoyed the writing style and the plot premise was interesting - I felt that there could have been so much more done with this to make it a stronger thriller and ultimately keep the momentum from the first part of this book.

 Not a bad book by any means and still enjoyed reading but was left hoping for more.
