The novel is split into two loosely interconnecting stories. In the first story a saxophone teacher becomes aware that Victoria, the older sister of Isolde, one of her pupils, has had a sexual affair with the music teacher, Mr. Saladin. While the adults believe that Victoria was raped, Victoria's fellow students believe that the relationship was consensual. They are forced to attend counselling provided by the school. Isolde, who is two years younger than the rest of the students, is forced to attend with the older girls. While there she develops an interest in Julia, who is rumoured to be a lesbian, because she deliberately provokes the councillor. The saxophone teacher invites Julia and Isolde to a concert and the two slowly become friends. The saxophone teacher believes that they might be having a sexual affair and reminisces about her own obsessive love with her friend Patsy, who owns the studio she teaches out of and eventually married a man. Meanwhile Stanley, a high school graduate, successfully auditions for the Institute, a prestigious drama school. While there he finds himself driven to the middle of the pack and is not thought of as being particularly talented. He begins to crave the attention and adulation of his teachers. The first year students are expected to put ona show of their own creation which the instructors are not involved in. They eventually settle on putting on a show about the scandal between Victoria and Mr. Saladin. While rehearsing Stanley runs into Isolde, coming from her private saxophone lessons. The two begin dating. A month into their relationship Stanley is called into the office of the Head of Movement who is told that the saxophone teacher contacted the Institute to complain about Stanley's relationship with Isolde, who is only fifteen. The Head of Movement also reveals that Isolde is Victoria's sister which Stanley had not previously realized. Terrified he meets with Isolde and has a fight with her, accusing her of implying that he raped her to her saxophone teacher. To make it up to him Isole takes her parents to Stanley's show, failing to realize what the play is about. After the show her family and Stanley and his father get together to discuss what has happened. In the aftermath of the affair Victoria returns to school and everything gradually goes back to normal. She asks Julia if she has slept with her sister and asks her to give her enough facts so that she can at least imagine what happened between them.
Themes
The Rehearsal describes theatric technique in great detail and uses what Catton describes as "themes of performance and performativity".
Critical reaction
The initial reaction in New Zealand was positive, but with reservations. Louise O'Brien in the Listener wrote of, "a new talent who has arrived fully formed, with an accomplished, confident and mature voice. This is a startling novel, striking and strange and brave." However, O'Brien thought that characterisation impaired the reader’s emotional involvement. The Rehearsal received positive overseas reviews. Ed Caesar in The Times speaks of The Rehearsal as imperfect, but praises “a starburst of talent”. Author Joshua Ferris called it "a glimpse into the future of the novel itself". The novel also won a range of awards including the 2007 Adam Award in Creative Writing, the Amazon.ca First Novel Award, the 2009 Betty Trask Award and 2009 New Zealand Society of Authors Hubert Church Best First Book Award for Fiction.
