Book does contain mature themes that may trigger some people and not be suitable for young kids. The earliest memory Sophia has is her drowning. How she felt trapped in the water that she had no escape. But here is the kicker, Sophia has never been to the ocean. The story follows Sophia trying to understand what her first memory is really about and if she actually ever did drown or if it was all just some weird misunderstanding. Sophia ends up visiting Bitter Rock to find answers about her earliest memory, but something else pops up along the way. Every year people go missing at Bitter Rock. They leave their spirits behind that echo onto everyone who visits Bitter Rock. The cycle has been happening for decades and no one knows why. Follow along on Sophia's journey to figure out what her earliest memory means and if it has some connection to all the disappearances from Bitter Rock.
