My Invisible Boyfriend by Susie Day
4 stars! This is a great book, with a main character who has a passion for detectives, especially Mycroft Christie, a debonair twenty-third century time traveling detective, with whom she has some illuminating, yet imaginary conversations. Heidi's problems started at the end of summer, when all her friends returned from enjoying their breaks somewhere exciting. The Leftover Squad has changed. Wild Ludo is, well, still wild, more more fashion conscious and less herself. Dai, a.k.a Big Dai, isn't so big anymore, thinks their old dedication to Mycroft Christie was "dorky", and has some serious muscles. Fili is more emo but less in a way, and was she flirting with the new goth kid? Heidi feels left out and so when Ludo think Heidi has a secret boyfriend, Heidi goes with it. Giving "Ed" a name, a ULife profile, and some (okay, maybe a lot) of Mycroft Christie's traits, making him the perfect boyfriend. ...
