Cadence Sinclair Eastman is part of the distinguished Sinclair family. Every summer the Sinclairs, headed by Cadence's grandfather Harris, gather at their private island off the coast of Massachusets. With her cousins Mirren and Johnny, and Johnny's sort-of stepbrother Gat, Cadence leads a decadent lifestyle, running riot on the beach at Beechwood Island without a care in the world, part of the self-titled Liars. But then Cadence is involved in an accident, one that leaves her suffering physical and mental pain, and has to come to terms with what has happened to her and the effects it's had on her family.
We Were Liars doesn't quickly tell you what has happened to Cadence, instead the story unravels slowly, like a rope whose separate strands are fraying and coming apart, and it's only towards the end you realise the rope is completely broken. I enjoyed the slow reveal - it gave me time to try and work out what was going wrong, to try and figure out why certain things (events, phrases, people) unsettled me so much.
