While in London visiting her mother, fifteen-year-old Miranda guiltily enjoys the company of a British boy while wondering why Dex is out of touch, but she returns home to find her friendships, love life, family, and math team are all in turmoil.
The Girl Genius is back and life has never been better! I, Miranda Bloom, finally have an almost-quasi-boyfriend, Dex McConnell, the lacrosse star of Orange Cove High. But when holiday break rolls around, and I jet off to visit my mother in London, Dex suddenly seems to lose all interest in me. Then there's Henry, the very cute and very available British guy, who complicates matters even more by making it clear that he's very interested in me. Things don't get any easier when classes start back up at Geek High. Between the dreaded math team competitions, an annoyingly love-struck best friend and a step-mother who seems to delight in making me miserable, it doesn't take a genius to see that the semester ahead is going to be tough.
