Where can I find a complete notes guide on Eleanor Catton's The Rehearsal?

The Rehearsal, Eleanor Catton’s first novel, was published in 2008. It tells the story of a music teacher’s affair with one of his students and the fallout that this generates throughout the school.
Music teacher Mr. Saladin has a sexual relationship with Victoria. Victoria is the older sister of one of the novel’s main characters, Isolde. Whilst the teachers and other adults believe that the relationship constitutes rape, Victoria’s fellow pupils believe that it was consensual. The students also use the relationship as the inspiration for their end-of-year school production.
The story is told from the point of view of the drama students and other students connected to the scandal in alternating chapters. It becomes unclear to the reader what is then reality and what is actually performance.
