Promontory fort

Mnemo knows the hidden chamber beneath the fourth stone. The chamber contains the drowned library of Clonboy. The library holds every book the sea took during the last drowning. The books are still wet. Their pages contain lives lost before the water rose. The girl must read one page and give one year of her life. She reads the page belonging to her mother. The mother returns changed, with salt in her voice and a new name. The girl loses one year but regains the woman who forgot her.
