TEEN LIBRARIAN'S REVIEW:
Frannie Falconer and Marcus Beauregard are best friends. These "brain twins" are so close they can basically read each other's thoughts and complete each other's sentences. When Frannie starts crushing on Jeffrey Osborne, a progressive, socially conscious classmate, Marcus helps her develop a plan to win Jeffrey over. Thus begins a modern day twist on the classic tale of Cyrano de Bergerac, where one friend uses another friend's words and ideas to make someone fall in love with them. Here, Marcus IMs Jeffrey night after night, all the while pretending to be Frannie. Jeffrey and Frannie have amazing chemistry online, but when they're hanging out together in person, both find it difficult to connect and have fun. Which only makes sense, since all those wonderful online conversations are actually being conducted by Marcus, not Frannie!
"M or F?" is a fun, frothy, lighthearted story about friendship, falling in love, and the dangers of making assumptions about people. Marcus and Frannie narrate alternate chapters, and both are amusing and entertaining characters. It's particularly nice that Marcus's homosexuality isn't treated like some awful, oppressive issue. It's just who he is, and it very believably complicates the story once Marcus finds himself falling for Jeffrey online. "M or F?" is essentially a comedy of errors, and most readers, from middle school up, will have a fun time watching Marcus, Frannie, and Jeffrey figure out exactly what's going on.
