In the mood for a summer mystery? We Were Liars, the new Prime Video series based on the novel by E. Lockhart, takes us to Beachwood–the private island owned by the Sinclair family–and the mystery of what happened at the end of Summer 16. The main characters are four cousins (and one non-relation) who call themselves "the liars" and have spent summers together since they were eight years old, a.k.a. Summer 8, playing and getting into trouble.
The liars grow up together until one summer changes everything for them and their family members. Like any show about a big family, it does take a minute to tell cousins from siblings and learn which child belongs to which parent. Here's what you need to know about the cast and crew of We Were Liars.
