Case of the Missing Mabel

Best friends Oliver Avery and Quinn Costa expected to have a pretty easy-going summer before starting fifth grade. But when Quinn's pet cat Mabel goes missing, the two kids will do everything they can to bring her home safe! That means working together, learning new things about animals and technology, and even braving the fickle and potentially dangerous southwest weather.

During their search, Oliver and Quinn discover that, unfortunately, Mabel isn't the only lost pet out there to find. Can the two of them use their skills and determination to help not just Mabel, but other wayward pets and pet owners in their community?
