Gelo ( Génesis # 1, 2006) av Wolfgang och Heike Hohlbein.
Från Googles :
A bordo de um navio em viagem entre a Cidade do Cabo, África do Sul, e Brisbane, Austrália. Ben, um jovem de dezassete anos, passa os dias morto de tédio... até que, diante da gélida Antárctida, o paquete de luxo é atacado por um sinistro navio-fantasma, transformando-se num cenário de horror, executado por uma tripulação ávida de sangue. Mas, quando o navio encalha na Antárctida, o pesadelo ganha contornos verdadeiramente tenebrosos. Debaixo do gelo imutável, habita um poder antiquíssimo e malévolo, cujo tempo acabou de irromper...
Det är den första boken av serien Génesis , där alla böcker har en bläckfisk som kramar kärleksfull en diamant / en planet på omslaget, som du kan se here .
Och från vår goda vän Google Translate, eftersom jag inte hittade en engelsk version av den (ursprungligen tyska) boken:
On board of a ship traveling between Cape Town, South Africa, and Brisbane, Australia. Ben, a seventeen-year-old, spends his days dying of boredom ... until, before the icy Antarctica, the luxury package is attacked by an ominous ghost ship, turning into a horror scene, executed by a crew greedy for blood. But when the ship is stranded in Antarctica, the nightmare becomes truly gloomy. Under the immutable ice, inhabits an age-old and malevolent power, whose time has just burst ..
Den här översynen innehåller många av de punkter du nämnde:
Potentially recommended(*), if you like: (a) spiders
[...]
There's also Sasha, the captain's daughter. She knows things but doesn't talk.
[...]
Range of settings: (a) a luxurious cruise ship on the way to Australia. (b) a meteorological station in the antarctic winter. (c) a secret laboratory harboring secret research.
[...]
Fact: When the monster dies, Sasha becomes able to talk (and interact/ respond to her surroundings). Conclusion:
A: She was never autistic in the first place, it was just the creature's supernatural influence being misdiagnosed (because doctors aren't always right). Which adds up to the repeating pattern of supernatural phenomena being discarded as such, and explained as something else (like Ben's premonitions and theories);
B: She never stopped being autistic, but the creature's supernatural influence has kept her permanently on the verge of overload, and now that it's gone she can talk and respond properly.
