This is similar to Waiting On Wednesday except that the books are necessarily not published at the moment. Some may be from a few years back and maybe even a rumored book every once in a while...
So the first book that I for Thinkin' About Thursday is:
Perfect Chemistry by Simone Elkeles
Description: When Brittany Ellis walks into chemistry class on the first day of senior year, she has no clue that her carefully created “perfect” life is about to unravel before her eyes. She’s forced to be lab partners with Alex Fuentes, a gang member from the other side of town, and he is about to threaten everything she's worked so hard for—her flawless reputation, her relationship with her boyfriend, and the secret that her home life is anything but perfect. Alex is a bad boy and he knows it. So when he makes a bet with his friends to lure Brittany into his life, he thinks nothing of it. But soon Alex realizes Brittany is a real person with real problems, and suddenly the bet he made in arrogance turns into something much more. In a passionate story about looking beneath the surface, Simone Elkeles breaks through the stereotypes and barriers that threaten to keep Brittany and Alex apart.

I first saw the book trailer of this on Stephanie Kuehnert. She was talking about whether or not she should make a book trailer for Ballads of Suburbia. She had this book trailer as an example of a good one. I saw it and had to find it somehow. But I can't afford it! I hope I can get it soon!
