Then she entertained a large part of the school with an in depth talk about writing her book Night Vision, a book that won the Young Adult Fiction Award at the 2015 LIANZA Children's Book Awards and also (and maybe more importantly) won the YA Children's Choice Award at the 2015 New Zealand Book Awards for Children and Young Adults.
Night Vision is such a good New Zealand story for kids - we have it in the library but you will need to reserve it as it is always out! Also try out Ella's trilogy Thieves - one of my favourite YA series.
