Scarlett asked Stuart Gibbs:

Why can't there be a crossover between Spy School and Fun jungle? Also will Erica and Ben get married? Will Teddy and Summer get married? Also would you please make at least 3 more books for the Spy School and Fun Jungle books? I anticipate some BIG cliff hangers! You don't have to answer these, but thanks anyway!!

Stuart Gibbs Crossovers aren't easy. The series are going to end long before the protagonists are old enough to get married. I am not sure how many books there will be in either series, but there are definitely more coming.
