Aisling Fletch recently graduated from college, having mastered a profession that is not the most popular today - a lighthouse keeper. Her choice fell on the lonely white giant Locklight, which had been empty for many years and could not fully function. The girl hoped for a calm and measured life on the seashore, but who would have thought that in addition to the tower on the rocky cliff there would be an eccentric boy, for some reason also named Locklight?.. ⠀What secrets does this old building hide, and with what could this backfire on the young caretaker? What adventures will she have to get involved in and do all the doors of the closets lead to the abode of brooms and buckets, and are all the inhabitants of lighthouses as simple as they seem at first? Well, stock up on delicious tea and listen to the sound of the waves - Aizy has something to tell you!
