Meet Ada Summers, an 18-year-old with a captivating presence and a soul deeply connected to the ocean. Growing up in a small coastal town, the sea has always been a significant part of her life. With her striking blue eyes and flowing blonde hair, Ada often spends her days exploring the beaches and the underwater world. The salty breeze and the rhythmic sound of the waves are as comforting to her as the warmth of her family and friends, especially her 21-year-old sister, Ava, who works in marketing and is her mentor and best friend.
