Con quest!

"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 TV star. 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 checklist. They volunteer at an Artist Alley booth, gathering cosplayers in enough colors to make a double rainbow, and actually finding something healthy to eat in the convention center! Can the twins work together when they start to disagree on how to compete? Will Fi find the Cat and Alex before their parents realize they're missing? Most importantly, can these ultimate fans complete the ultimate Quest?"--Provided by publisher.
