Does anyone know this book, basically this little girl runs away from her abusive mother to a park and this older girl finds her and takes her in then the little girls other brother comes into the picture and they start dating and then I’m pretty sure the two girls get kidnapped and this description is a mess but I read it like 5-6 years ago but I can’t think of the name and I want to read it again. (I know I said I read it 5-6 years ago which is when I was like 6 or 7 but it’s definitely an adult book so I thought I should mention that)
