Book I read in early/mid 1990's

I read this book when I was in elementary school in the US in California. I think it was required reading.
It was about two siblings sold/given by their parents to slavers, sec trafficking, etc. Not sure if it was a sister and brother or two sisters. Possibly set in Vietnam or other early 1900s run down country. Was told from older siblings point of view.
I can't remember really solid details about it so hopefully someone knows it. Thanks!

Vampire, horror, teens, bullying

There's this book I read a few years ago. It's about a fat kid who was 12-13? And he was being bullied in school and he met a vampire who appeared to be a girl and around his age. Turns out the vampire was a boy and his name was Elias or something like that. He had a 'parental' figure in his life who killed little kids for the boy and he was a pedophile I think. Certain scenes I remember is when the fat kid stole some chocolates from a store, when he met elias in a playground and when they were communicating in Morse code. PLease heeelp I want to read it again, it was an amazing book.

Part sci-fi part crime fighting

Read a book in 2002 when I was in the 6th grade about this little girl who was electrocuted by a wall socket and developed telekinesis and telepathy. I remember her abilities were tested as a child and specifically those cards where she had to guess what was on the other side that the person was looking at. It then goes to modern day and she's helping battered woman by using her abilities. One husband I think tries to murder his wife and the lady saves her.
