Honestly, i was hoping for a meet-cute story but this definitely wasn't that.
I must say that i liked to have the stories of the two sisters and the points of view of both but i feel like the book could have been easily made in two different stories, one for Molly and a totally different one for Sarah as we get so much from her life.
I could only think about how can one woman get herself in so many troubles in a span of a few weeks? I totally approved her independence and wanting to give up at her relationship with Niall, her secrets kept till the last minute, her friendship with Liam and her relation with Molly and what they are planning. All of this had my head spinning around, because i really see them as a normal person with a normal life but not to that extend to get to a point of using a love formula.
As for Molly, i feel that she gave up to quick, and honestly, i haven't felt the chemistry between them.
Overall it's a well-written book for sure, the characters are okayish but i just couldn't connect with them.
