Nutrients for a Flower
Great Job Kit!
Read the story now
You start off strong with a very punchy opening! The beginning is hook, line, and sinker in the truest sense, and really drives in that Amelia is in a low point in her life. First the tumor, then her betrayed love, and finally her odd family situation.
Moreover, you do a fantastic job building the world around Amelia, with specific people and specific events to connect back to each individual you introduce. Notably, I do caution against adding too many characters since readers can only remember a few names at a time. Or if you plan for adding many characters, find a way to tie off loose ends with each character, or just give the character some specific trait/event related to the main character (Amelia) for the reader's mind to connect back to. Though this has limited effect since readers won't remember every single name. For future reference, I'd suggest making a list of characters (for your own use) to check when you introduce a character, and how many chapters it's been since you mentioned them. If its been more than a few chapters, you probably need to include a 3rd person blurb/flashback of that character so the reader knows who you're talking about.
As for serious critiques, the biggest thing holding your book back is grammar. Though readable, there are many instances where the wording makes things confusing. In addition, your sentence structure makes the dialogue feel choppy, and you could make it have better flow with a few simple edits. For example, in the summary you write "He said, sounded like nervous." where a simple "He said nervously." would flow much better. I highly recommend using a grammar checker (Hemingway app is a good free one). As a final note, be careful with tense. There are times in the story where you write in present tense, then switch to past tense despite Amelia making present time observations. But the grammar checker should pick up on this (hopefully). If it doesn't I recommend putting the story into a text-to-speech program so you can "hear" the mistakes.
But please don't let the critiques get you down! Overall, this is an amazing story! The plot is well thought out and the characters complex. The grammar/syntax is holding back the flow of the story, so you can think of edits as polishing your diamond in the rough. If you want to stick to a nature metaphor, it's a flower that needs some help to fully bloom.
Good luck and keep writing! I look forward to seeing a more polished version!
