This didn't work for me. It wasn't what I expected from the synopsis. 

It took 25% to get to the dating game part and by then we had already met the very obvious end game love interest for Jemima. 
 I also felt it was too obvious where each of the girls would end up at the end. 

The pact felt too slow at the beginning. I felt the plot was less about the dating game itself, which I was actually interested in, and more about the girls personal dramas. Which I wasn't interested in. The book just didn't spend enough time on the dating game part and the fun stories that could have come from it. Instead it went in a direction of showing how horrible the girls were and how they all needed to work on themselves. 

The girls were all so unlikeable. It didn't help that there was no real character growth until the last chapter. I didn't care if they all ended up single. 
 The only character I liked was Chance. He deserved better. 

Overall this was underwhelming.
