The Hunger Games Novel Series
I love this series so much. I'm torn between Divergent and this one but definitely Hunger Games is my number one favorite. Katniss is a bad-ass heroine, I love her! The best book for me on this series is Catching Fire.
The Selection Series
Recommended by a friend and it made me really curious. The series is like the reality show The Bachelor but he's not just an ordinary guy, he is a Prince. Prince Maxon is looking for a wife and the only way is through Selection. This novel series is consists of five books. But for me, it ended on The One, which is the third book. I like the series since it was really entertaining but there are parts where I hate America (main protagonist).
If I Stay Series
A heartwarming & heartbreaking story. This series is all about love, tragedy, heartbreak and forgiveness. It is beautifully written. There's one quote that I love on the series "Sometimes you make choices in life and sometimes choices make you."
