Nikki really wants to have an awesome birthday party, however the money she needs for it goes over budget. She had originally wanted something smaller, but her best friends convinced her to throw a pool party. When her little sister, Brianna, starts selling dog treats, she teams up with Nikki and they earn a lot of money. With this money, Nikki gets enough to have her birthday party and have some money leftover as well. Nikki also has decided that she is going to tour with her friends instead of going to Paris. Overall, this book was funny and I recommend it to people who enjoy the Diary of a Wimpy Kid series or the other Dork Diaries books. I rate this book 5/5.
