THERE ARE SPOILERS! Cadence (Cady) is the heir to the very rich Sinclair family fortune. Her grandfather has a island where they spend every single summer at. When Cady is eight years old her anut Carrie meets a new guy (whom she is in love with) and he brings his nephew Gat to the island as company for Carrie's son Johnny. Johnny, Cady, Gat, and Mirren (whom is another cousin) create this group called The Liars (that only ever gets together at the island). When Cady is 15 something happens to the liars that causes her to almost kill herself. She then spends the next 2 years in Vermont or in Europe. When Cady is 17 years old she finally convinces her Mother to let her go back to the island so she can discover what happened 2 years ago. Also during those 2 years the other liars NEVER ONCE contacted her while she tried to contact them. So when Cady returns they are there acting like its normal and they haven't been seperated for 2 years without any contact what so ever. Basically after a lot of talking and some love. Cady discovers that Johnny, Gat, and Mirren died in a house fire.
