It begins with the normally healthy Beth - aged-care worker, wife of David, mother of Lettie and Gem - feeling vaguely off-colour. A locum sends her to Dr Yi for some tests. 'There are a few things here that aren't quite right,' says Dr Yi, 'and sometimes it is these little wrongnesses that can lead us to the bigger wrongs that matter.'

Beth is sent on to Dr Twoomey for more tests. Then to another specialist, and anotheraReferral after referral sees her bumped from suburb to suburb, bewildered, joining busloads of people all clutching white envelopes and hoping for answers.

But what is actually wrong with Beth - is anything, in fact, wrong with her? And what strange forces are at work in the system? As the novel reaches its stunning climax, we realise how strange these forces are.

Unnerving and brilliant, Some Tests is about waking up one morning and finding your ordinary life changed forever.
