A middle-grade comics convention adventure about fandom, family, and finding your place in the world. Cat and Alex are excited to be at the world's most popular comics convention-and they're even more excited to compete in the Quest, a huge scavenger hunt run by their favorite nerdy celebrity. The big prize: a chance to meet him! The twins ditch their older sister Fi and set off to find geeky clues, tackle nerdy challenges, and cross as many items as possible off their Quest list, which includes: volunteering at an Artist Alley booth, gathering cosplayers in enough colors to make a double rainbow, and even finding something healthy to eat in the convention center! Can Cat and Alex work together even when they disagree on how to compete? Will Fi find the twins before their parents realize they're missing? Most importantly, can these ultimate fans complete the Quest? Available in softcover and hardcover.
