I'm in LOVE
I absolutely LOVE the whole concept of what you have written for this story!
Read the story now
The plot seems pretty unique and from the chapters I have read, I can safely say, that this plot is a very origional idea! What I also love is how the author talks about the realistic side of love and that it isn't all sunshine and rainbows as one might say, so this was also a very big green tick!
Not only that, but the way you portrayed Lacey in the second chapter was brilliant because as the reader, we immediately see her flaws and I think this is VERY important for when writing a story as there is no such thing as a perfect human, we all have flaws and I think as an avid author and reader, it is very important to demonstrate those flaws to the reader to show them that the character is just like them, so yet again well done!
However, linking to the characters, I was disappointed with the lack of character description. There were so many ways you could have entangled description in, and yet, in the chapters I read, I couldn't find any except for a bit about the man Lacey bumps in to (who I am also already shipping with). The man (I don't want to be a spoiler) is shown to be very handsome, which all readers can appreciate, so I am hoping as the two grow closer, we'll get to see some of his flaws.
I also think that the opening chapter should be changed slightly to create a hook for the reader. There isn't anything overly exciting that makes the reader desparate to read on, which was a bit of a bummer, so I think that could definitely be improved on (perhaps a prologue of Lacey and her ex?) And it should be something exciting or/and something that leaves the reader questioning and wondering, therefore embedding the urge to continue reading.
Not only this, but you also head hopped in the second chapter which is one of my biggest pet peeve about writing. It is basically where you hop from one character's brain to another unnecessarily. If you NEED to do this, do it in a seperate chapter. When you swapped from Lacey's pov to the Marcus's, it not only confuses the reader causing them to have to scramble to get seated comfortably again, but it reveals things that you shouldn't include, like how another person is feeling (in this case). One of the best thing about writing a novel is keeping the reader in suspense and you do this one way by preventing the reader from knowing what another person is thinking about the MC (main character). But don't worry, we all do this, but just be aware of it in future!
I also just want to mention that you don't have to put speech and dialect in italics. That should really be saved for a character's thoughts or a word in a conversation that is being stressed. I really advise you to look at books because you see that no books do this and if you want to get published (which I am assuming you do) you'll have to change that.
Apart from this, there were just a few grammar mistakes like spelling and punctuation, but we all do this, so don't get too worried about it until you come round to editing it. There were also just a couple of sentences I found that could be changed round to make a bit more sense, e.g. "I asked Taylor he had eaten" —> "I asked Taylor IF he had eaten." It's things like this which just help to make the story flow better.
Apart from that, I think this novel is off to a brilliant start! Don't give up as it has amazing potential and I'm excited to see how far you go!
