Wizardmatch by Lauren Magaziner

My name is Lennie, and I couldn’t believe my mom chose Michael to compete against our cousins in the Wizardmatch! Poppop told her to pick him, but she should have stood up for me! It's so unfair! I deserve to be the next Prime Wizard, and I need to do something big. I found Uncle Humphrey secretly living in the borderlands, and he's the only person who believes in me. He's going to become my mentor and teach me how to master my power of invisibility. But the Wizardmatch is still unfair, and it's got all the relatives at each other's throats. I can't even stand to be around my little brother anymore. My uncle has a plan that might solve everything, but it will require me to use my power in ways I've never imagined. 

It was strange to see a grandfather being such a jerk toward his kids and grandkids. He was self-centered, superficial, and played favorites. Even though Lennie was the protagonist, she was clearly motivated by anger and jealousy. I didn't have a lot of empathy for her character, as her actions often didn't make her much better than her grandfather. She behaved in a selfish manner despite mentioning some unfairness to her older cousins and females. Her temper drove her behavior, but it was nice to see more positive qualities emerge when her plans fell apart. Be prepared for some goofiness, as the magic was used in unusual ways. Poppop's estate included a moat made of chocolate pudding, a cemetery made of goulash, and one floor in the castle was made of jelly. One cousin was able to eat things and cough up birds, while another had the ability to control his hair. Overall, the story was entertaining and created a fun tale. It provided a positive message regarding respect and family relationships.
