Thoughts: 

First off I'm going to admit that I did scan through the last few chapters and found out the ending before reaching the end. I was disappointed,  but I didn't read the whole book either so I could have missed something important. But I was so disappointed!!! I mean why??? I was shipping the two because I felt like they complimented each other, but when you did what you did, that just blew the whole story for me. Sadly.

I won't spoil it for others, so I can't say, but just know I was very disappointed.*points index finger at you while narrowing eyes* Anyway, you have a good story going right up until chapter fourteen. I'm not saying that the story wasn't good after fourteen. But that's as much as I've read. For all I know the second half could be great but due to my love ship being crushed I had to stop reading. 

Your plot is very interesting and intriguing. You do need to go back and edit this slowly, sentence by sentence.  I recommend reading it backwards to catch your errors. Reading out loud helps as well. Arabella was a well developed character in my opinion. I enjoyed reading about her. Cole was just irresistible yet damaged. Mason was the cupcake, waaay too sweet. All your characters were well developed in a sense, some more than others.

In my opinion, you did make a mistake of letting Arabella open up to Cole, only to have her end up with Mason. I thought Mason was too sweet for Arabella. I know Arabella deserves someone good in her life, but I felt like if she was going to end up with Mason then you shouldn't have invested so much into her and Cole. Because it crushed me to know the two weren't together. 

I recommend rewriting so it looks like Mason is her saver than Cole. This is completely a fantasy romance, and for me I look to escape reality.  This story was too realistic in a way that she doesn't end up with Cole but Mason. I mean she was the first woman Cole took an interest in. And I felt that Arabella was perfect for Cole. They both had damaged lives and they both challenged each other. I mean it seemed like they were going to be together, but then BAM. They're not. Sighs, I'm just really disappointed which made me stop reading. I think that's one of the reasons your readers have slowed down. The way you set it up was good, but it also tore my image of who will end up with who by the halfway point. I had begun suspecting that she was going to end up with Mason in chapter fourteen, which is why I looked ahead. Mason is too sweet for Arabella in my opinion. He doesn't compliment her. He is just too good to really fit in with Arabella. 
I can't stand Scott in the beginning,  but I supposed he had his reasons. I loved the idea of a woman being a good thief, yet having to survive off anything she finds on the streets. The story was insightful in that area. 

Something else you do is switch point of views when the story is clearly about Arabella. I'm not saying you shouldn't switch povs but that you show write your blurb as to represent the three individuals included, Arabella, Cole, and Mason. The way you set up the blurb had me thinking I'll be reading a story completely from Arabella's viewpoint. You also need to work on using various words for things. For example, you use 'messing' a lot instead of spilled or some other variation for messing up. 

Overall, I would have kept reading hadn't you ended it the way you had. If you have any questions don't hesitate to ask me. I'll be glad to answer.
