Madeline Fitzgerald is an eighteen year old girl bound for college. She's had an online friendship with a guy for years, who she knows nothing about. All she knows is that he lives in England with a cat.
One day, he asks for an address so he can send her something in the mail. After offering it to the guy, Maddie finds herself a plane ticket bound to London some weeks later. From there, she discovers way more about him than she expected.
