Now that 9-year-old Willis Wilbur has discovered his destiny as a life coach, he's looking forward to signing on more clients (preferably human ones, not just guinea pigs). When Willis and his classmates are tasked with creating a passion project - an opportunity to present an idea they love and share it with the whole school - Willis enlists his very smart friend, Margo, and his number one best friend, Shelley, to make the Willis Wilbur App, also known as the first-EVER life-coaching app. Willis is confident he's going to become a millionaire...except he doesn't know anything about technology. Or worse yet, coding. And then he discovers something even more horrific: Shelley wants to do her own project on horse therapy with her new, extremely weird, absolutely awful friend, Colt. Willis must learn hard but rewarding lessons about jealousy, realistic goal setting, and putting your pride aside to ask for help.
