Harriet is socially inept and a klutz to boot, so when her best friend Nat (who has always wanted to be a model) makes her go to a clothing show on a school trip, she is hesitant, especially when it involves a five hour bus ride with fellow geek/stalker Toby. When Toby manages to throw up on both girls, they are kitted out in soccer (football- this is a British book) uniforms and set loose on the fashion show. Harriet manages to knock over several booths and end up under a table with a very good looking boy, Nick, who works for a modeling agency. Wilbur is the scout for that agency and is taken with Harriet, wanting her to come and interview with a famous designer to be the face of her new line. Harriet's step mother is against this, but her father, a rather irresponsible guy who works in advertising, is so excited about the opportunities that he lies to his wife about taking Harriet to Moscow, and she goes off on a modeling job with Nick. There are problems at school concerning her geekiness and a mean girl there, but Nat forgives Harriet her modeling career and stands up for her.
This is a series of four books. I don't know how I missed them when they first came out.
This is an amusing geek-to-chic story that is fast paced and clean enough for middle school girls. The Louise Rennison books seem to have run their course, and there's always a subgroup who likes British books. The parents in this are quite fun, too.
