As soon as I started reading FIRSTS, I was hooked! The story itself is incredibly intriguing, the writing is fabulous, and the characters all jump right off the page! I especially loved that it challenged stereotypes about sex, and about female sexuality. 
 I absolutely LOVED Mercedes. I'm nothing like her, but I really appreciated the honesty of her narrative. She was snarky (which I loved!), and dishonest with her friends, but as a narrator, she held nothing back. While certain parts of her past were revealed later in the story, I really appreciated the transparency that her narrative had when she was considering things, and I loved seeing her slowly open up to the people in her life, too. 
 I loved that Mercedes for the most part was in control when it came to sex. Her personal reasons for helping out virgins are something that you'll have to read the book to find out about yourself, but she definitely did everything that she did to help them. While her desire to help guys give their girlfriends a good first time was honourable in a way, it did bug me that she was sleeping with guys that had girlfriends. I loved that she was in control of her sexuality, but I did wish that she wasn't sleeping with guys in relationships. There were also a couple of minor moments where I really wish Mercedes had stuck up for herself and stuck to her original decisions, but overall, I was still really happy with this story. 
 As I said before, I loved how FIRSTS challenged preconceived notions about sex that so many people have. I LOVED that it pushed boundaries, and I loved that even Mercedes' notions about relationships were challenged throughout the story. I loved seeing her friendships grow, and I especially loved when she finally allowed people to see the real her. She changed a lot throughout the story, and that was because she finally decided to start letting people in. Her friendships with Angela, Faye, and Zach were my absolute favourite part of FIRSTS. I did appreciate and love the romance too, but I loved that friendship had such a high importance in the story. 
 FIRSTS was a wonderful story! The characters were fantastic and complex, and I absolutely loved the writing. I loved how Laurie Elizabeth Flynn challenged so many different preconceived notions about sex, and I'm really looking forward to whatever she writes next! :D
