I like the premise. Opening with one brother killing another for their father's inheritance is a strong start and invokes a lot of immediate power (classic struggle, understandable motives, apparent bad-guy, although family drama can be murky in a productive and interesting way).
I also think giving some back-story (the story of the kid's mother and abusive father) is useful. Understanding the family dynamic that led to fratricide-levels of dysfunction is probably justified... although it is a LOT of background given that the story seems to be about the brothers more than the mother / father.
I had two main issues with this.
- A lot of the sentence wording and structure is awkward. I did not get lost -- I understood the basics about what was going on, and was able to follow the essentials of the plot, but you are going to want to work closely with an editor to clean things up.
This is not fatal, but it was distracting and took me out of the story pretty frequently. There were some key factors I was unsure about (was Alena cheating? Lying about Zac going to the hospital? I wasn't completely clear on how to read the sentences that seemed to explain that)
That said, if English is not your first language, this was good enough to keep me reading. It's something to work on and fix -- not a reason to abandon the project or anything like that.
- I felt like I had a lot of information about Jeff (the dad), and understood his background, his weaknesses, etc. I barely had a handle on the kids (Luke and Zac) .
Now, this is the start of their story, so you have room to develop them, but jumping DIRECTLY into the murder plot in the first scene that shows them interacting felt very abrupt and a bit disorienting.
I didn't feel like I had a handle on either character (are they adults? They visit their father monthly, so that sounds like it, but I wasn't sure). Do they trust each other? I wasn't even sure where they were (their father's house?)
