Riley Anderson swears she will never fall in love with Sammy Hong.



After all, every girl on earth already has.



But when Sam shows up next door with a scandal on his heels, their childhood friendship is rekindled and Riley feels the pull toward something more. But Sam is only here until the end of the summer and then he's leaving to face the consequences of his actions and return to the world of pop stardom.



The pair, accompanied with Riley's rambunctious younger cousin, make a list of all the things they want to do while Sam's in town, but as they work through the activities and dodge rabid fangirls, letting Sam go may be harder than Riley ever imagined.
