@studnavy I think the book is going great, but I would say this:
Try to break the chapters into more paragraphs, instead of just one or two long ones.
You have a lot of things happening (Mateo’s sickness, Maya’s dad, Maya and Jamie, Claire, Daria, Lucia) and you should probably wrap one or two up to concentrate on the important ones. The biggest thing is Jamie and Maya, so work on their dynamic, since they might be making a little progress, and maybe get some resolution on a few others so they don’t detract from the main plot? But if Jamie opens up with Maya then you have a lot of options with dates and dealing with parents
