Limited Time Freebie - Silently Screaming by Dawn Husted

I came across this e-book being given away as a freebie for a limited time from Friday, 10th to Sunday, 12th April 2015 on Amazon. I was intrigued by the blurb so I promptly downloaded it and have added it to my TBR shelf on Goodreads.

Genre : Young Adult

(the book cover and blurb source - Goodreads)

Blurb : 

It's the spring semester of their senior year at Centerville High. Despite drastically different upbringings, Nikki and Caroline have been best friends since they were ten years old.
Whenever Nikki isn't in school, she's either at work or visiting Caroline. Nikki's only chance at a normal future is to save enough money so that she can move out after graduation. But when she chooses to do the unthinkable for extra cash, the ramifications are deadly. 
Caroline's life is anything but picture perfect, unless her parents can help it. When they find out she's pregnant, her mom encourages her to get an abortion, but Caroline's determined to raise the baby with her boyfriend Tod. When the pressures of school and life become too much for her to handle, what will she do?
