|As I was reading, the descriptors used to indicate the speaker, such as "the frizzy-haired girl", "the bespectacled ringleader", and especially labels that simply use the character's ethnicity, like "the Latina", quickly became distracting. I understand the desire to avoid repetition (I used to do this a lot too), but more often than not, it's better to use the character's name. Throwing those variations in every once in a while doesn't hurt, but when they are used frequently, it makes it hard to figure out who is talking. Also, referring to a character as "the Latina" or "the Vietnamese girl" feels a little dehumanizing. I would find a more natural way to indicate the race of the characters, like including cultural details when you mention their families or hobbies.
That out of the way~ I love the premise! You created a group of distinct characters and threw them together into this situation which really mixes things up. I realize this is just one chapter of a longer work, so I'm missing a little bit of the background (I should go back and read the rest, lol). Even without knowing everything, I can tell there is enough mystery here to keep readers engaged. I get the feeling that Jay and the others are *quickly* going to end up in over their heads!
Another strength is how the conversations between the characters feel very natural. Everything they say sounds like something people would actually say to each other. Through the dialog, you indicate which characters have known each other for years and who is brand new to the group. I also was intrigued by Bian, who is so anxious (maybe even on the autism spectrum?) that she communicates to her best friends through text. I've never met a character like that before, and her quirk reflects the mannerisms of people I have met who are extremely introverted and/or have autism.
Keep it up!
