It's a book for young adults, and the main theme of the book is this boy (I think between 8 and 13) who has a babysitter who's being beaten by her boyfriend. He tried to help her escape, but she emotionally could not leave him and had to turn around. She also had a baby by this dude (the boyfriend, not the kid). I also remember that the kid rode a Day-Glo bike, because his mom was overprotective.
I have Googled to no end and CANNOT figure this out. Does anybody know the title of this book?
Thank you, "Cracker Jackson" it is. You guys are magic.
