The Glow

When Lily loses her job, she also loses the last thing that kept her from heading to Southend-on-Sea, in search of her estranged sister, whom she suspects has joined a dangerous new cult.
The Glow are so named for their bioluminescent plastic island, which floats in the North Sea. In a near future rife with plastic pollution, they have no shortage of material to keep their island growing. It's rumored that the inhabitants draw power from an asteroid that once landed there-but anyone who has ever gone in search of answers has disappeared.
Will Lily make it to the island and find her sister? If so, will she make it back out alive?
