Видит ли моряк маяк?

Can the sailor see the lighthouse?

There will be spoilers.
Lampeshka is about 10 years old, she lives with her one-legged father at the lighthouse. Every evening the girl goes up the steps and lights a fire on the lighthouse, it’s as if it’s her duty, but at the same time it’s not really her responsibility. The caretaker is a father, and Lampeshka simply cannot help but help him. And then one day the house runs out of matches, Lampeshka forgot to buy them on time, and as luck would have it, on that day the twilight thickens extremely quickly and a severe storm begins. But the lighthouse is not lit. Trouble does not take long to arrive: a ship crashes on the rocks in the bay. Whose fault is it - Lampeshka, who did not go to the store for matches in advance, or her father, who should have controlled this? It doesn't matter whose. The ship cannot be returned, and the city is demanding damages.
The father is locked in a lighthouse, where he will work for free for the rest of his life, and the daughter is sent as a servant to a wealthy, but very gloomy house, about which there are rumors throughout the city that a monster lives in it. And now a lonely girl with her things tied up in a small bundle finds herself in this terrible place where she will have to work for seven years. Is life terrible for her here? Well, in general, no, it’s not that bad: there are other servants here, quite kind people, she has a clean room, her work is also okay - ordinary household duties, she even has a day off once a week. But the house clearly hides a secret, which Lampeshka is in no hurry to reveal, but she still finds out.
In the tower above there lives a strange creature, evil, aggressive, but weak. Instead of legs, he has a fish tail, and therefore cannot boast of dexterity. If you go to him and stay a little longer than you should, he will be rude, attack, bite, but nothing more. Doesn't look like a full-fledged monster. And Lampeshka decides to talk to him. Pisces - that’s what she calls the boy, and this is exactly the boy, her age - well educated, smart and embittered towards the whole world. He calls his tail a commissure and believes that someday it will become ordinary legs if he performs the most difficult, painful exercises every day. Pisces is the son of the owner of the house, and the owner is not just anyone, but an admiral. An admiral who lost his ship due to a faulty beacon. An admiral who is ashamed of his son. An admiral who, many years ago, brought back from a voyage a young, beautiful wife with a tail instead of legs.
I won’t tell you anything more, I retold the general line, but it is not the only one in the book: there are also dramatic plots, well-written characters and interesting details.
Don't worry about the child's psyche: everything will end well.
Fascinating, tense, psychological story for children from 10 years old - "Lamp" .
